Your Ovulation Timing Depends On The Length Of Your Cycle
Ovulation is when one of your ovaries releases an egg.
You only ovulate once per cycle. You may release more than one egg at a time . But youll never ovulate, then ovulate again without having a period in between.
Ovulation occurs near the middle of your cycleafter your follicular phase, and before your luteal phase. The events play out like this:
Your cycle starts with your period.
Day 1 is considered the first day of steady bleeding . Periods last 5 days on average, but anywhere between 2 and 7 days is normal.
Your follicular phase varies in length.
It starts when your period starts , and ends with ovulation. The length of your follicular phase depends on how quickly youre able to make enough of the hormones that activate your folliclessacs in the ovaries that each contain an egg. Once activated, one dominant sac will rupture and release its egg.
Ovulation takes about 1 day.
The release of an egg triggers the production of hormones that prepare the body for a potential pregnancy.
Those pregnancy hormones rise and fall during your luteal phase.
They rise during the first half of the luteal phase, and you may feel a natural high and more energy as a result. Then they fall during the second half, and you may experience PMS symptoms.
If no egg was fertilized that cycle, pregnancy hormones are no longer needed. Their levels will continue to fall, which will trigger a period, and the cycle starts over again.
Ovulation: How Many Days After A Period Is It
If your cycle is always exactly 28 days long, ovulation occurs about 14 days after the first day of your period. But according to the research, if your cycle is always exactly 28 days long, youre practically a unicorn.
One study measured the cycle lengths of women who identified as having regular menstrual cycles, and found 46% of them actually had cycles that varied within a 7 day range. An additional 20% had cycles that varied within a 14 day range . Couple that with the ~18% of women who identify as having irregular menstrual cycles , and its safe to say that most peoples cycles are not always exactly 28 days long.
Although cycles lasting anywhere between 21 and 45 days are considered normal , you cant accurately predict your ovulation timing by simply counting 14 days after your period starts if you deviate from the average 28 day cycle.
More detective work is needed, and this article is your guide. It covers:
- Why ovulation timing depends on the length of your cycle
- How to know when ovulation occurs if your cycles are longer or shorter than 28 days
- Why ovulation isnt just a fertility concernits a big deal for your period, too!
You’re Born With All Your Eggs
Each month, you ovulate an egg. But these eggs arent created new monthly. Youre actually born with all the eggs youll ever have. With time, the number of eggs in the ovaries decreases.
At birth, a baby has about 2 million eggs. By the time she reaches puberty, this number is down to around 500,000. As you age, the genetic stability of the eggs decrease. This is why women over age 35 are at a higher risk for:
- experiencing miscarriage
- having a child with a genetic disease
Because you are born with all the eggs you will ever have, some cancer treatments can cause permanent infertility. If the cancer treatments kill the eggs in your ovaries, you wont be able to produce new ones later.
Egg freezing can help preserve fertility for women facing cancer treatments.
Egg freezing is also being used in women who want to delay parenting until after 35. They freeze their eggs in the 20s, in hopes of using their younger, healthier eggs later in life.
However, using egg freezing to beat your biological clock is controversial and does come with risks. Also important to know: banking your frozen eggs does not guarantee a future successful pregnancy.

How To Track Your Ovulation Cycle:
A womans monthly cycle is measured from the first day of her menstrual period until the first day of her next period. On average, a womans cycle normally is between 28-32 days, but some women may have much shorter or much longer cycles. Ovulation can be calculated by starting with the first day of the last menstrual period or by calculating 12-16 days from the next expected period. Most women ovulate anywhere between Day 11 Day 21 of their cycle, counting from the first day of the LMP. This is what many refer to as the fertile time of a womans cycle because sexual intercourse during this time increases the chance of pregnancy. Ovulation can occur at various times during a cycle and may occur on a different day each month. It is important to track your cycle and fortunately, there are a number of free fertility charting tools available to help women identify their peak fertile days.

Calculate The Length Of Your Menstrual Cycle
- Make a note of when your next period starts. This is the first day of your cycle.
- Then, make note of when your period comes again in the following month. This is the beginning of the next cycle.
- When you count the days in between, this gives you the length of your cycle.
Here’s an example:
- Period starts: January 1
- Next period starts: January 31
- Days in between : 30 days. The menstrual cycle length, therefore, is 30.
You might want to do this for more than one month, as menstrual cycles can vary in length from month to month. This will also help you determine if you have an irregular cycle, in which you may skip periods for a month or more at a time. An irregular cycle will make predicting ovulation more difficult.

Tracking Basal Body Temperature
People can work out roughly when they are going to ovulate each month by tracking their daily basal body temperature. For most people, the temperature reading will be 12 days before their period starts.
To use this method, a person needs to measure and record their temperature each day using a basal body thermometer. It is best to take the reading at the same time every morning, ideally before getting out of bed in the morning.
Rectal thermometers are usually more reliable than oral thermometers. Because the change in temperature is typically very small, it is important to use a thermometer with an accurate and easy to read scale.
Basal body thermometers are available in pharmacies, and a person can also purchase them online.
There are also many smartphone apps that allow people to easily record their basal body temperature and track their fertility cycles. Some thermometers even come with their own apps.
Tracking basal body temperature over multiple cycles can help a person predict when ovulation is likely to occur.
Days 07 Past Ovulation
Ovulation is the moment an ovary releases an egg.
As soon as an ovary releases an egg, the luteal phase of the menstrual cycle begins. The luteal phase ends with a menstrual period unless pregnancy occurs.
Women will not experience any pregnancy symptoms during the earliest part of the luteal phase. This is because pregnancy does not occur until the fertilized egg implants into the wall of the uterus.
During the luteal phase, the body produces more progesterone, which is a hormone that helps sustain an early pregnancy. The levels of progesterone peak at 68 days after ovulation, even when a woman does not become pregnant.
Progesterone levels can affect a womans mood and body this means that after a week or so, they may experience similar symptoms in early pregnancy as they do before a period.
When a fertilized egg reaches the uterus, it implants itself into the wall of the uterus. This is called implantation and marks the start of pregnancy. Implantation typically happens 612 days after fertilization.
This is the time when women may begin to experience pregnancy symptoms, including:
- breast tenderness
- increased nipple sensitivity
- headaches and muscle aches
However, these symptoms may also occur in those who are not pregnant. This is because of the increased levels of progesterone that are present during the last stages of the menstrual cycle.

How Is My Estimated Date Of Ovulation Calculated
On average, a woman with a regular 28-day cycle ovulates on about the 14th day of each cycle. If a womans cycle is longer or shorter than 28 days, the predicted ovulation date is changed accordingly. For example, during a 24-day cycle , ovulation takes place on about the 10th day. Similarly, changes are made in the opposite direction for cycles longer than 28 days. Stress, illness, and other things can also affect the timing of ovulation. Irregular cycles or cycles that are shorter than 21 days or longer than 35 make calendar prediction of ovulation unreliable.

Natural Cycles And Ovulation
By measuring your temperature orally most days, its possible to identify a shift in basal body temperature, which happens right before ovulation takes place. This is how Natural Cycles works to calculate your fertility.

How Knowing Your Fertile Days Helps
Since you can only become pregnant after you have ovulated , the goal is to abstain from unprotected sexual intercourse during this time.
Once you know when your most fertile days are, you should not have any unprotected sex during the five days leading up to and including the day that you ovulate, and during the one day after ovulation.
Why five days + one? Sperm can live inside the female body for up to 5 days, so… let’s say “Jennifer” ovulates on Day 12. If Jennifer has sex on Day 7, Day 8, Day 9, Day, 10, or Day 11, there can still be sperm living inside of her. So when her egg is released on Day 12, there can be plenty of sperm waiting to fertilize it.
Same goes with Jennifer having sex on Day 13 . After she ovulates, her egg is “open for business” for about 24 hours . If Jennifer happens to ovulate in the afternoon or evening in Day 12, her egg can still be joined by a sperm during that 24 hour period.
So if she has sex the next afternoon or evening, her egg may still be still “accepting visitors.” Abstaining from unprotected sex the entire day after ovulation is also a wise idea.
Determining The Best Time To Have Sex To Conceive
So, your fertile window may last up to 10 days, but clearly, if you want to get pregnant, you want to have sex as close to ovulation as possible.
How can you time sex for your most fertile days during your fertile window?
There are many methods of tracking and predicting ovulation. Your best options include ovulation test kits , body basal temperature charting, and checking for fertile cervical mucus. An ovulation day calculator may also help provide an estimate, but isnt always most accurate of methods.
That said, research has also found that timing sex for pregnancy can cause excessive stress in some couples. Timing sex for conception may be good for getting pregnant but not great for your relationship. Thats important to consider.
According to the research, having sex when you have fertile raw-egg-white-like cervical mucus is the best way to time sex for pregnancy.
Another option is to have frequent sex and not worry so much about the exact ovulation day. But again, this can put more strain on a relationship than may be warranted and isnt a reassuring option for those who have been trying for some time or know there may be an underlying fertility problem.
Unless you are in the midst of fertility treatments, and your doctor has asked you to have sex on a particular day or set of days, you may want to consider dropping ovulation detection.

When Does Ovulation Happen
For the majority of women, ovulation happens once every month, approximately mid-way through their cycle, around 14 days since their last period .
But in reality, ovulation can happen almost any time from day 11 to day 21. This is because the average length of your cycle might be anywhere between 21 and 35 days.
Lets not forget that your body isnt always predictable either. Sometimes you ovulate on a different day just because thats your bodys natural rhythm that particular month, or youre under stress or undergoing an emotional upheaval, travelling, or even changing your lifestyle habits.
Because of this natural variation, it becomes much harder to identify exactly which day will be the magic number for you.
Signs Of Ovulation To Look Out For
Here are the seven main ovulation symptoms lookout for:
- Your basal body temperature falls slightly, then rises again.
- Your cervical mucus becomes clearer and thinner with a more slippery consistency similar to that of egg whites.
- Your cervix softens and opens up.
- You may feel a slight twinge of pain or mild cramps in your lower abdomen.
- Your sex drive may increase.
- You may notice some light spotting.
- Your vulva or vagina may appear swollen.

When Do You Ovulate After Your Period
Whether youre planning to become pregnant in the most natural way possible, or experimenting with natural family planning methods, its essential that you know exactly when you ovulate after your period.
Miss that tiny window of opportunity and you could face yet another disappointing month without being able to fall pregnant. Or you might misjudge your bodys signals and accidently conceive when you werent planning to.
So the big question is, when exactly do you ovulate after your period? And how on earth do you know when youve got the date right? Lets take a look.
How To Know When Youre Ovulating
Knowing when you ovulate can help you plan for sex at the right time and improve your chance of getting pregnant. You can keep track of your menstrual cycles on a chart, in a diary, or on a free period-tracker app on your smartphone.
To work out the length of your menstrual cycle, record the first day you start bleeding . This is day 1. The last day of your cycle is the day before your next period begins.
Some people think the menstrual cycle and a period are the same thing.
A period is when you bleed .
A menstrual cycle starts on the day when a period starts and ends the day before the next period. A cycles length is considered normal if its between 21 and 35 days. They can vary between women and from one cycle to the next.
- Working out your average menstrual cycle length
If your menstrual cycles are different lengths you can work out your average cycle length.
The number of days in a womans menstrual cycle can vary month to month. Periods are not always regular. It can be useful to work out an average cycle length, based on the length of three menstrual cycles, to estimate when youre most likely to be ovulating.
If you add the number of days in three cycles and divide the total number by three, it gives you your average cycle length.
Sarah tracked her last three menstrual cycles by counting the time from the first day of one period, to the day before the next period.
Cycle 1 was 28 days Cycle 2 was 32 days Cycle 3 was 27 days
28 + 32 + 27 = 87
