Is it easier to get pregnant after your period

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, it’s important to realize that an egg can survive for about 24 hours after ovulation, and sperm can live inside a woman’s body for three days—though sometimes it’s possible for them to survive for five days. “

How long should a normal menstrual cycle last?

An average menstrual cycle lasts 28 days, defined from the first day of menstrual bleeding to the first day of bleeding of the next period. However, irregular periods are very common.  An irregular period is defined as a cycle that varies by more than seven to nine days. 

There are several reasons why women may have abnormal periods, which can include fibroids, ovarian cysts, polyps, and even something as common as stress. 

“If you’ve constantly had an irregular period, please contact us for an appointment to determine the underlying cause and initiate treatment,” said Dr. Martinelli. 

When does ovulation start?

If you have a normal 28-day cycle, ovulation should occur about 14 days before you start your next period.

When can I become pregnant after my period?

If you have intercourse five days before ovulation until one day after ovulation, you can become pregnant. You’re much more likely to become pregnant if there are live sperm in the fallopian tubes during ovulation.

Fertility Awareness and Family Planning

Some women use fertility awareness as a method of natural birth control. One of the tools used is something called the Standard Days method. This establishes that if you have a period that is between 26 to 32 days long, days eight through 19 will be your most fertile days. However, this method is most effective when you have regular menstrual cycles. 

If a woman has a regular period and uses the method perfectly, less than one to five women out of 100 will become pregnant. However, the key words here are “perfect use.”  The typical use rate is different. Typical use means that the methods may be done incorrectly or measured inconsistently. In the first year of this typical use, 12 to 24 women out of 100 will become pregnant. (American College of Obstetricians and Gynecologists)

Yes, it's possible to get pregnant right after, on, or even just before your period. The likelihood of getting pregnant varies depending on timing and the length of your cycle.

If you're trying to get pregnant, the best time to have sex is just before or during ovulation. If you're not trying to get pregnant, use reliable contraception no matter which day of your cycle it is.

Here's a rundown of your chances of getting pregnant during your period, and on the days before and after it.

Can you get pregnant on your period?

Yes, but it's unlikely. It's possible to get pregnant during your period when:

  • You have a very short menstrual cycle (the time from the first day of one period to the first day of your next period).
  • You have long periods.
  • You were bleeding around the time of ovulation (spotting between periods) and mistakenly thought it was a regular period. If you had unprotected sex at that time, you could conceive.

Here's why you could get pregnant during your period:

Ovulation happens during the middle of your menstrual cycle – anywhere between 7 and 19 days before your period starts. During ovulation, an egg reaches maturity in one of your two ovaries, the ovary releases the egg into your abdomen, and it gets sucked into the nearest fallopian tube, where it can survive for about 24 hours. Conception occurs when an egg and sperm meet in a fallopian tube.

A typical menstrual cycle is 28 days, which usually leaves a good few days between the end of your period and the start of ovulation. But some women have cycles as short as 22 days. If you have a short cycle or long periods, you could ovulate right after your period ends. And because sperm can survive in your reproductive tract for up to five days, if you have sex during your period, it's possible that live sperm will be there when you ovulate, ready to fertilize the egg.

Can you get pregnant right after your period?

Yes. Immediately after your period is still not the ideal time to get pregnant, but you are more likely to conceive at this time than during your period. That's because you're closer to the time when you will ovulate.

Again, two factors can increase your chances of getting pregnant right after your period:

  1. A short menstrual cycle
  2. A long period

The shorter your cycle and the longer your period, the more likely it is that you'll be fertile during the last few days of your period or in the days just afterward.

Can you get pregnant right before your period?

Yes, but it's unlikely, and chances are even lower that you could conceive during this time than while you are on your period or right after it.  That's because the time you are fertile has probably passed.

However, if you have a menstrual cycle that is shorter than the typical 28 days, there are fewer days between ovulation and the start of your next period during which you are not fertile. That means your chances of getting pregnant right before your period are higher if you have a shorter cycle and lower if you have a longer cycle.
