Ovulation Date: How Is Ovulation Calculated How Many Days After My Period Do I Ovulate
So now that we know what it is, how many days after your period can you expect to ovulate? Well, the complicated thing is that everyone is different but usually, you can tell when you will ovulate by the length of your cycle.
The first day of your cycle is the first day of your period, and typically, most people will ovulate anywhere from 7 to 21 days into their cycle. Where exactly ovulation falls within that bracket depends on how long your cycle is. Normal menstrual cycles can range from every 21 days to every 35 days, says Dr. Boyle. The time from ovulation to the next menstrual bleed will always be about 14 days thats generally the same for all women. But the time from the beginning of a period until ovulation is what can vary.

Understanding your menstrual cycle is crucial to defining when you ovulate and calculating when you are most likely to get pregnant.
Women should be aware that if they have an irregular period, it can make the ovulation days difficult to determine. Said Dr. Martinelli. When examining fertility, its important to realize that an egg can survive for about 24 hours after ovulation, and sperm can live inside a womans body for three daysthough sometimes its possible for them to survive for five days.
Your Ovulation Is Not A Clock
Any factors that influence the hormonal pulsing in your brain can influence your ovulation. Environmental and internal factors like stress, diet and exercise changes can lead your ovulation to happen slightly earlier, or later, or not at all. Your period may then come earlier or later as well, and be lighter or heavier.

How Long Is The Menstrual Cycle
Womens cycles can vary in length and from month to month, but the average is around 28 days. Its normal to have regular cycles that are longer or shorter than this .
It doesnt matter how long your cycle is, most women will ovulate around 10 to 16 days before the start of their next menstrual cycle.
Right After Your Period Ends
Many women look forward to having contraception-free sex right after their period ends. Its true that its unlikely youll get pregnant a day or two after menstruation stops, but given the lifespan of sperm and the challenges around predicting ovulation exactly its not at all impossible.
This is especially true if you ovulate earlier than you usually do, or if you have a naturally short menstrual cycle of around 21 days.

Get To Know Your Cervix
Ovulation isnât an entirely hidden process, and there are some definite physical signs of ovulation. As your body senses the hormone shifts that indicate an egg is about to be released from the ovary, it begins prepping for the incoming hordes of sperm to give the egg its best chance of being fertilized.
The other cervical ovulation symptom you can watch for is a change in mucus. Cervical mucus, which youâll notice as discharge, carries the sperm to the egg deep inside you. After your period ends, youâll have a dry spell, literally you shouldnât expect much, if any, cervical mucus. As the cycle proceeds, youâll notice an increase in the amount of mucus, with an often white or cloudy appearance and if you try to stretch it between your fingers, itâll break apart.
As you get closer to ovulation, this mucus becomes even more copious, but now itâs thinner, clearer and has a slippery consistency similar to that of an egg white. If you try to stretch it between your fingers, youâll be able to pull it into a string a few inches long before it breaks . This egg white cervical mucus is yet another sign of impending ovulation.
Can You Get Pregnant During Period
Can you ovulate right after period? You already know the answer. Can you get pregnant on your period? Yes, you can get pregnant during your menstrual period. However, getting pregnant during a menstrual period is highly unlikely. If this occurs, the ovulation process occurs very early during a menstrual cycle and you need to have unprotected sexual intercourse which led to conceiving.
Usually, the egg is still developing while you are having your period. However, many factors can complicate the normal ovulation process and make you ovulate earlier than normal. A hormonal imbalance, a poor diet, thyroid gland disorders, use of certain medications and even stress can have a great impact on the ovulation process, making you ovulate and get pregnant during period.
Mistaking Spotting for a Regular Period
However, another chance to get pregnant during “period” is that you are not having your period.
Spotting between menstrual periods is common for women who have irregular menstrual periods. Spotting around the time of ovulation is often a sign of ovulation along with other ovulation signs such as abdominal pain located just on one side, etc. Spotting can also occur due to breakthrough bleeding, especially within the first few months after starting to use hormonal contraceptives.
If you are not planning a pregnancy, use a contraceptive birth control method. Also, dont forget to use protection against sexually transmitted diseases and practice safe sex.

Im Pregnant But Have Some Bleeding Is This My Period
Implantation bleeding sometimes happens in pregnant women around the time their period would have been due. Implantation is when the developing embryo plants itself in the wall of your womb. An implantation bleed is very light bleeding that is usually pinkish and sometimes brown. Not everyone will have an implantation bleed.
Its common to have light bleeding or spotting without pain before 12 weeks. This isnt often serious, but you should contact your doctor, midwife or Early Pregnancy Unit immediately to be checked, just in case.
Truth: Caffeine Does Not Prevent Conception
Its debatable whether you need to completely quit caffeine when youre trying to get pregnant. The research hasnt been clear. For example, a study in Denmark found that tea drinkers were slightly more likely to get pregnant, soda drinkers were slightly less likely to conceive, and coffee seemed to have no impact on fertility.
What does all that mean? We dont know. For now, though, most agree that less than 300 mg of caffeine a day should be fine. One cup of coffee is less than 300 mg.

Can You Be Fertile On Your Period
While its extremely unlikely, the simple answer is yes. Women are not able to conceive whilst on their period, but sperm survives within the female reproductive system for up to five days. This means that a tiny fraction of women do have a small chance of becoming pregnant from unprotected sex during their period. It all depends on the length of your menstrual cycle simple, right?
Lets take an example, say you have a menstrual cycle shorter than 28 days. You have sex towards the end of your six-day-long period and ovulate shortly after, then there is a chance that some of the sperm survive and you could get pregnant. So while getting pregnant is unlikely, its technically possible if you dont know your fertile window.
What About Right Before Your Period
The likelihood of getting pregnant right before your period is extremely low. For women with a typical 28- to 30-day cycle or longer and their cycles are regular, it is fairly safe to say your ovulation occurred between Day 11 and Day 21. The egg is only available for 12 to 24 hours for conception.
This means the days right before your period are the safest to have sex without the expectation of getting pregnant. The number of safe days right before your period go up with longer cycles and lessen with shorter cycles.
If you wait 36 to 48 hours after ovulation, you should be beyond the possibilities of conception. The further you are from ovulation, the less likely your chance for conceiving. This is not the time to have sex if you are trying to conceive. Its still a good time to enjoy intimacy with your partner.

How Soon Can I Get Pregnant After Coming Off The Pill
You can get pregnant as soon as you come off the pill but if youre trying to get pregnant, its a good idea to wait until youve had a natural period. This will give your body time to adjust and give you a chance to make sure youre ready for pregnancy. Make use of our pregnancy planning tool to see what else you can do.
How Can You Get Pregnant On Your Period
The chances of getting pregnant when you’re on your period are low, but they’re not zero. So how could a pregnancy happen at the same time your body is deciding its not pregnant?
Lets break it down: At ovulation, your ovary releases an egg into your fallopian tube, where it can live for 24 hours awaiting fertilization before it travels to the uterus. Meanwhile, the uterus is building up a lining just in case it needs to host a growing embryo.
If egg meets sperm during ovulation and implants in that lining, bingo baby on board. If not, your body sheds both lining and egg .
Most womens menstrual cycles last about 24 to 28 days, from the first day of their period to the first day of the next period. Because the egg can survive for 24 hours after ovulation and sperm can live inside a woman for up to five days, a woman can get pregnant starting five days before ovulation and ending a day after.
Ovulation usually occurs 14 days before the first day of your next cycle which, if you have a 28-day cycle and a week-long period, leaves you a week between the last day of your period and the first day you ovulate.
But what if you have sex on the last day of your period and you ovulate a few days early? There could still be viable sperm inside you, and you could get pregnant.

Length Of Your Menstrual Cycle
Your menstrual cycle begins on the first day of your period and is a critical component in determining when you can get pregnant. Most women have a 28-day cycle from the first day of one period to the first day of the next, but it can vary. Some have cycles as short as 21 days, for example. Technically, your cycle is considered regular if you have your period at least every 24 to 38 days, but that degree of variation can make estimating your fertility period challenging.
If you skip periods entirely or have cycle lengths that fall outside the regular range or change significantly from month-to-month, then you have what is known as an irregular cycle. Unfortunately, that will make it harder to pinpoint when you are likely to ovulate. If you are having difficulty conceiving and want to calculate the best estimate for when you could become pregnant, you may have to track your periods for a few months to determine an average length or some sense of a pattern for your cycle.
Check Your Basal Body Temperature
It’s also a good idea to pay attention to the signs that your body is ready to ovulate. Checking your basal body temperature is one way to do this.
The BBT is your temperature first thing in the morning. Just after you ovulate, it rises slightly — sometimes by less than a degree — and stays higher until your period starts. If you record your temperature every day, you can spot the subtle changes that mean one of your ovaries has released an egg.
To take your BBT, you need to:
Use a basal body thermometer. It’s more sensitive than a standard one and will show temperature changes down to a fraction of a degree. You can get them at many pharmacies for less than $20.
Take your temperature at the same time each morning. Always do it before you get out of bed. Even getting up to go to the bathroom can affect your body temperature. So can smoking, drinking, or getting a bad night’s sleep.
Remember, your BBT won’t tell you exactly when you’ve ovulated, and it may take a couple of months before you start to see a pattern. You’re most likely to get pregnant 2 or 3 days before your ovary releases an egg, and then another 12 to 24 hours after that. When your temperature has spiked for 3 days, your chances of conceiving drop.

My Menstrual Cycle Is Still Irregular Has The Pill Affected My Fertility
Its unlikely the pill has caused any fertility problems, but it can sometimes cover up problems you already have, such as missing periods or PCOS .This is because the pill prevents the ovaries from releasing an egg , so although its normal to experience period-type bleeding on the pill, you dont have a real period.
Contact your GP if youre still having irregular periods 3 months after stopping contraception.
How To Accurately Calculate When You Ovulate
Whilst this might sound rather confusing, it really doesnt need to be. Because there are several easy methods you can use to accurately predict and monitor how long after your period you ovulate.
Step #1: Track Your Periods
Firstly, keep track of your periods for at least six months. You dont need any kind of fancy equipment to do this, just your favorite calendar and a pen, or even an online calendar. You can also download an app to help but I usually find that simple is best.
On the first day of your period, make a note in your diary. Period Day 1 is what works for me. Then count 22 days forward and make a rough note of this too so you can best keep track of the length of your cycle. Then when you start to menstruate, you can pinpoint the exact length of your cycle.
Then simply repeat the process. After several cycles, you should start seeing a pattern that is unique to you.
Step #2: Calculate Your Possible Ovulation Days
Once you have worked out your typical cycle length, you can turn your attention to your ovulation dates.
If youre usually quite regular, you can get a rough idea by taking the length of your usual cycle, subtracting 16 days and then adding four. If your cycle lasts 27 days, so you would do the following:
27-16=11 then11+4= 15.
Then you can conclude that you are most likely to ovulate on day 15 of your cycle .
Obviously this method isnt fool-proof, so do be careful.
Step #3: Watch For Signs Of Ovulation

How Do I Know Im Ovulating
Pinpointing ovulation can be tricky. There are several methods people use to track their menstrual cycle and estimate when ovulation occurs. Since each method has its drawbacks, its always best to use more than one for the most accurate answer.
Menstrual cycle
Ovulation happens at around the midpoint of your cycle if you have a 28-day cycle . However, a normal cycle is anything between 21 and 35 days, so this means ovulation is unique to your menstrual cycle. Keep track of your cycle on paper or on an app on your phone for several months. Take note of any unusual symptoms. Most people ovulate 14 days before their period begins, regardless of cycle length.
Calendar method
People using the calendar method to predict ovulation, analyze six months of menstrual cycles to determine when theyre fertile. To calculate when you may be ovulating, you find your shortest cycle and your longest cycle in a six month period. You subtract 18 days from your shortest cycle and 11 days from your longest cycle. These two numbers give you the days in your cycle youre most fertile. For example, if your cycle lengths are 31 and 18, your fertile time is day 10 to 20 of your cycle.
Cervical mucus
Basal body temperature
Ovulation kits
Ovulation kits work similarly to at-home pregnancy tests because you pee on an indicator strip in the comfort of your own home. They work by detecting LH in your pee. LH is the hormone that surges before ovulation. A positive result means youre about to ovulate .
Sex Right After Your Period
While you may assume that your odds of getting pregnant are slim in the first few days following your period, you are actually moving into a new fertility window. Researchers have shown that a person’s chances of conception jump starting a week after the start of their last period and rise steadily after that, peaking around day 15 LMP.
Your odds of getting pregnant in the days just following your period rise when you have a shorter length between periods because that usually means you ovulate soon after your period ends. Research has shown that people with a 23-day menstrual cycle, for instance, have a 9% chance of ovulating on day 10 LMP. That means they are fertileable to get pregnantbetween six and 11 days after the start of their last period.
Remember, even when you are in your suspected fertile window, that does not mean you will necessarily get pregnant from sex. Structural problems with your uterus or fallopian tubes or issues with either your eggs or your partner’s sperm can prevent conception and fertilization. If you are timing sex to get pregnant and having trouble after several months, consider talking to a fertility doctor about tests you can take to better understand how to maximize your chances of conception.
