Examples Of Most Fertile Days
The fertile period is the six days leading up to and including ovulation, and the one day after you ovulate. You are most fertile the three days leading up to and including ovulation.
Here are some examples to help you calculate your most fertile days. Remember, these results will be most accurate if you can reliably predict when you ovulate . So, you have figured out that:
- You have a shorter cyclethere are 21 days between periods. This means that you will most likely ovulate on Day 7. So, your most fertile days are Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, and Day 8.
- You have a regular cyclethere are 27 days between periods. This means that you will most likely ovulate on Day 13. So, your most fertile days are Day 8, Day 9, Day 10, Day 11, Day 12, Day 13, and Day 14.
- You have longer cyclethere are 33 days between periods. This means that you will most likely ovulate on Day 19. So, your most fertile days are Day 14, Day 15, Day 16, Day 17, Day 18, Day 19, and Day 20.
Tracking Ovulation To Find Your Fertile Window
There are many methods of tracking and predicting ovulation so you can try to figure out when you are most fertile. An ovulation day calculator may provide an estimate, but isnât always the most accurate of methods, especially if you have irregular periods.
Some ways to try to pinpoint your ovulation period at home include over-the-counter ovulation predictor kits, body basal temperature charting, and checking for fertile cervical mucus.
Ovulation predictor kits increase your chance of getting pregnant by 40%, according to a review of research. Each kit comes with five or so test strips or sticks, and manufacturers typically recommend you test your urine for several days leading up to your suspected ovulation day. This makes this method can potentially costly, especially if you have somewhat irregular periods and you have to test for many days on end.
Among no-cost home ovulation-tracking methods, checking the texture of your cervical mucus may work best. According to research, people who had sex when they had slippery, egg-white-like cervical mucus were two to three times more likely to conceive than those who had scant or absent mucus secretions .

When Does Ovulation Happen
If your menstrual cycle lasts 28 days and your period arrives like clockwork, it’s likely that you’ll ovulate on day 14. That’s halfway through your cycle. Your fertile window begins on day 10. You’re more likely to get pregnant if you have sex at least every other day between days 10 and 14 of a 28-day cycle.

Basal Body Temperature Recording
This method uses the fact that your basal body temperature rises by 0.4-1.0Â°C after ovulation by which time it is too late to optimize the chances of conception in that menstrual cycle2. To use this method accurately, you have to take your basal body temperature first thing every morning before moving out of bed, and it will take several menstrual cycles before you start to build up a picture of your fertility window. There are also many factors, like sleep cycles changes, travel, and alcohol consumption that can change your BBT. Studies have shown that using a womans basal body temperature to predict her fertile days is less than 70% successful.
Determining The Best Time To Have Sex To Conceive
Unfortunately, there’s no completely accurate method to detect that you are about to ovulate. It’s possible for an ovulation predictor kit, body temperature charts, and cervical mucus patterns to all indicate a slightly different ovulation day.
In a study of people with regular, 28-day cycles, ovulation occurred most commonly on day 15 after the start of the last menstrual period , followed by day 16 LMP and day 14 LMP . Researchers found a 10-day spread of observed ovulation days even among a group of people with “clockwork” cycles, and a similar variation for people whose cycles were a little longer or shorter.
Another group of researchers set out to pinpoint the most commonly fertile day in the menstrual cycle across the general populationincluding those with irregular cyclesusing menstrual period surveys and ultrasound measurements rather than ovulation signs. They found a sharp rise in the probability a person will conceive beginning at day 7 LMP, reaching a maximum probability of conception of 13% at day 15 LMP. By day 25 LMP, the statistical probability of conception is zero, according to the data.

How To Tell When You’re Ovulating
Since it’s such a small window, pinning down when you start to ovulate can be tricky. Here are some tips:
- Track your cycle: To start, try tracking your cycle. Ovulation takes place around 14 days before your period begins. Count back from when your period is expected to arrive to find out when you should ovulate. If you have a 29-day cycle, you’ll ovulate around day 15, but if you have a longer cycle of 35 days, you’ll ovulate around day 21, says Minkin.
- Monitor your cervical fluid: When the texture is creamy and the color is white, that indicates that you’re approaching ovulation, and when the fluid becomes slippery, stretchy, and clear, it’s a sign that you may be ovulating.
- Take your temperature: Another strategy is to take your basal body temperature, which is your body temperature at rest. Measure it in the morning, when you’re still in bed, before eating or doing any activity. During ovulation, your temperature will rise slightly, by about 0.5 to 1 degrees Fahrenheit.
- Ovulation predictor kit: The most accurate way to predict ovulation is with an ovulation predictor kit, says Minkin. These urine tests are available over-the-counter at drugstores and detect the presence of hormones that indicate ovulation. Minkin recommends the First Response ovulation test for its accuracy and ease of use.
On Which Days Of Your Cycle Can You Get Pregnant
There are just six days during your cycle when your chances of getting pregnant are the highest the five days that lead up to ovulation and the 24 hours after ovulation. Sperm can live in your body for up to five days, while the egg lives for no more than 24 hours.
The key to determining the best time to try to get pregnant is to know when you ovulate. The precise timing of ovulation is hard to define, as it can happen at different times in each cycle.
Ovulation is when your body releases a mature egg from the ovary. This egg then travels down your uterine tube to be fertilized. The egg is more likely to be fertilized if the sperm is in your uterine tube already. Once fertilized and attached to the uterus, it will create an embryo, which will grow into a baby.
Your most fertile time consists of the five days leading to ovulation and one day after it. Having sexual intercourse during this window gives you the best chance of conceiving.

Calculate Your Fertile Window
To calculate your Fertile Window, you need to determine what day you ovulate.To do this, you need to know the length of your menstrual cycle . To calculate this you should note how many days have passed from the first day of bleeding in your last period, to the first day of bleeding in your next.From this figure, subtract 14 days from the end of your current cycle to determine the day you ovulate.If you have irregular menstrual cycles, or your cycle length varies from month to month, it will be difficult to calculate your ovulation date. Ovulation urine tests may be useful, and you should consider seeking further advice from your GP or a Fertility Specialist.
What Is The Basal Body Temperature Method Of Determining Fertility
Basal body temperature is your temperature at rest as soon as you awake in the morning. A womanâs basal body temperature rises slightly with ovulation. So by recording this temperature daily for several months, youâll be able to predict your most fertile days.
Basal body temperature differs slightly from woman to woman. Anywhere from 96 to 98 degrees Fahrenheit orally is average before ovulation. After ovulation most women have an oral temperature between 97 and 99 degrees Fahrenheit. The rise in temperature can be a sudden jump or a gradual climb over a few days.
Usually a womanâs basal body temperature rises by only 0.4 to 0.8 degrees Fahrenheit. To detect this tiny change, women must use a basal body thermometer. These thermometers are very sensitive. Most pharmacies sell them for about $10.
The rise in temperature doesnât show exactly when the egg is released. But almost all women have ovulated within three days after their temperatures spike. Body temperature stays at the higher level until your period starts.
You are most fertile and most likely to get pregnant:
Two to three days before your temperature hits the highest point 12 to 24 hours after ovulation
A manâs sperm can live for up to three days in a womanâs body. The sperm can fertilize an egg at any point during that time. So if you have unprotected sex a few days before ovulation, you could get pregnant.

More Ways To Predict The Most Fertile Days After Period
Because a womans cycle is not always exactly 28 days and many women have irregular menstrual cycles, there are other things you can pay attention to in order to identify when you are ovulating. Things like the cervical mucus and your basal body temperature can help you tell exactly when you are ovulating, so you can get pregnant or avoid getting pregnant, whichever you are looking for.
1. Watch Cervical Mucus Changes
The consistency of the cervical mucus changes throughout the menstrual cycle. After having your period for five days, you will have about 3-4 days in which you have little cervical mucus. The moistness of the mucus increases every day so that the wettest day is about day 9 of your cycle. The mucus at this stage is easily recognizable. It should be clear, stretchy, slippery and should have the appearance of egg whites. You need this type of cervical mucus in order for the sperm to travel up into the uterus. Ovulation generally happens when you’ve had the stretchy type of mucus for about 1 to 2 days.
2. Record Your Basal Body Temperature
Before you ovulate, the temperature of your body stays about the same when you check it every morning before getting out of bed. As you near the ovulation time, there may be a dip in the basal body temperature followed by a spike in temperature after you ovulate. This spike in temperature indicates that you have just ovulated.
3. Use Ovulation Predictor Kits
4. Notice Abdominal Pain or Spotting
5. Feel Breast Tenderness
Understanding Your Menstrual Cycle
Your menstrual cycle begins on the first day of your period and continues up to the first day of your next period.
You’re most fertile at the time of ovulation , which usually occurs 12 to 14 days before your next period starts. This is the time of the month when you’re most likely to get pregnant.
It’s unlikely that you’ll get pregnant just after your period, although it can happen. It’s important to remember that sperm can sometimes survive in the body for up to 7 days after you have sex.
This means it may be possible to get pregnant soon after your period finishes if you ovulate early, especially if you have a naturally short menstrual cycle.
You should always use contraception when you have sex if you don’t want to become pregnant.

When Should I Ovulate
You may be wondering: When do I ovulate? Ideally, a woman will ovulate 14 days before her next expected period. If your cycle is unusual or you know that your luteal phase is more or less than 14 days, this may be different for you.
To find out when you should ovulate, in addition to using an ovulation tracker, you need to pay close attention to your body.
- First you need to figure out your average cycle length. If its unpredictable, a trip to your health care provider can be helpful to rule out any underlying medical issues that might be affecting your cycle.
- Next, you should calculate your luteal phase by paying attention to ovulation signs and symptoms.
- Once you have that information, you can enter it into the ovulation calculator and tracker to get a much better idea of when you should be trying to conceive
Treatment For Irregular Ovulation
If your doctor has determined that youre not ovulating regularly, the next step is often, but not always, treatment with Clomid. Clomid is a popular fertility drug that has few side effects and has a good pregnancy success rate.
However, be sure your doctor checks your male partners fertility and your fallopian tubes first. That means a semen analysis for him and an HSG for you.
You may be eager to just move forward with Clomid. But if something else is also keeping you from getting pregnantlike blocked fallopian tubes or male infertilityand those issues are not treated, then you will go through Clomid cycles for no reason.
If your doctor wont check your tubes and your partners fertility health before prescribing Clomid, go to someone else who will. Your partner may need to see a urologist for the semen analysis. Then, after the test, you can return to your gynecologist to try Clomid.
Its worth taking the time to get the necessary ovulation and fertility tests done early. This will help determine the best course of action for fertility treatment for you and/or your partner and increase your chances of successfully conceiving.

What Are The Main Signs Of Ovulation
Ovulation is the process of when the egg is released from the ovary. After it is released, it moves to the fallopian tube, where it stays for around 24 hours and waits for the sperm.
The most common signs of ovulation are:
Luteinizing hormone increases a few days before ovulation which causes the egg to be released – this usually happens 24-36 hours before ovulation
Body temperature rising
Sharp pain on one side – also called Mittelschmerz
Changes in saliva due to the amount of estrogen
Changes in cervical mucus to be clear and stretchy
Some women dont experience ovulation symptoms, but it depends on your cycle.
Track Your Basal Body Temperature
Your basal body temperature, or BBT, that is. Taken with a special, basal body thermometer, basal body temperature is the baseline reading you get first thing in the morning, after at least three to five hours of sleep and before you get out of bed, talk or even sit up. Your BBT changes throughout your cycle as fluctuations in hormone levels occur. During the first half of your cycle before ovulation, estrogen dominates.
During the second half after ovulation, there’s a surge in progesterone, which increases your body temperature as it gets your uterus ready for a fertilized, implantable egg. That means your temperature will be lower in the first half of the month than it is in the second half.
Confused? Here’s the bottom line: Your basal body temperature will reach its lowest point at ovulation and then rise immediately about a half a degree as soon as ovulation occurs. Keep in mind that charting your BBT for just one month will not enable you to predict the day you ovulate but rather give you evidence of ovulation after it’s happened. Tracking it over a few months, however, will help you see a pattern in your cycles, enabling you to predict when your fertile days are and when to hop into bed accordingly.
Many women do find this approach a bit frustrating and it is important to know that studies have shown that the timing of ovulation does vary among women after the dip in temperature. Ovulation predictor kits are more precise.
