Pregnancy can occur up to 3 days (72 hours) after sex, as sperm survive in the female reproductive system. If you ovulate early or have a short cycle, you could conceive shortly after your period. Sperm can live up to 5 days, so pregnancy is possible even during your period.
It is possible for some people to become pregnant just a few days after their period ends. This occurs if they release an egg during that period, which is known as ovulation. Ovulation is the process by which your body prepares for a potential pregnancy.
Always remember, if you want to get pregnant, timing is everything.
How Many Days After Period Can You Get Pregnant?
Women can get pregnant at any point in their menstrual cycle. However, the probability of conception is high from 5 days before ovulation to 2 days following.
During ovulation, the ovaries release the eggs, which travel down to the uterus; if they meet with sperm, fertilization happens, causing pregnancy. If not, the unfertilized eggs break down the uterus line and bleed, which is menstruation.
- Ovulation occurs around day 14 if you have a 28-day menstrual cycle, but some women have a shorter menstrual cycle, which is 21 days. You can conceive after a period ends because you ovulate a little earlier. If you have an irregular cycle, you can get pregnant just after your period.
- Women can get pregnant at any point in their cycle if they have engaged in unprotected sex.
- The chance of getting pregnant right after the period depends on the length of your period and how short your menstrual cycle is.
- For example, if you have sex toward the end of your period, you may be close to your fertile window, especially with a short cycle. Sperm can survive up to 7 days, so if you ovulate soon after your period, sperm from intercourse during your period can fertilize the egg once ovulation occurs.
- The days before and after menstruation are the least fertile days because ovulation, the release of an egg, takes place 10–16 days before the start of your period, where the egg can live only up to 24 hours.
- Since an egg is not available during menstruation and sperm only survives up to 7 days, conception is unlikely during this time.
Can You Get Pregnant Right After Your Period?
Yes, you can get pregnant right after your period, but it is rare. It is dependent on a number of variables, including the duration and regularity of your menstrual cycle and the precise time of your ovulation.
The possibility is high if you ovulate earlier than usual or if you have a short menstrual cycle of 21 days.
Basics of Reproductive Cycle:
On a 28-day menstrual cycle, ovulation occurs around 14 days before the start of the following menstrual cycle. If you have sexual contact every day between days 10 and 14 of a 28-day cycle, your chances of getting pregnant increase.
In general, your chances of becoming pregnant are increased if you have sex one to two days before ovulation.
| Phases | Days of the cycle | Levels of Fertility |
| Menstruation Phase | Days 1 – 5 | Least Fertile |
| Follicular Phase | Days 6 -13 | Low to moderate fertility |
| Ovulation Phase | Day 14 | Highly Fertile |
| Luteal Phase | Days 15 – 28 | Low to least fertile |
Can You Get Pregnant if You Have Sex During Your Period?
No, you will not get pregnant if you have sex during your period, possibly. Because your ovulation date remains several days away, your chances of becoming pregnant during this period are reduced.
At the same time, during menstruation, the uterus lining, which is called endometrium, is shed. This process clears out the uterus and also washes away any sperm that may have reached the uterus.
But there are a few exceptions, like people with shorter menstrual cycles who ovulate early may get pregnant if they have sex towards the end of their period.
Although the chances of getting pregnant are low, they still exist.
What About Right Before Your Period?
The probability of getting pregnant right before the period is low. On a regular 28-day menstrual cycle, ovulation occurs around 14 days before the start of the next menstrual cycle, and the egg is only available for fertilization for 24 hours.
It also means that having sex right before your period is one of the safest days to avoid pregnancy.
Your chances of getting pregnant reduce as you get farther away from ovulation. Having sex right before is not a good idea if you are trying to get pregnant.
When Are You Most Fertile?
If your cycle lasts 28 days on average, deduct 14 days from when you expect your next period to begin. Try to have sex every other day on days 12 and 14 around that time.
Your chances of getting pregnant are lowest right before and right after your period. You may still be able to conceive during this window of time if your menstrual cycle is shorter than the typical 28-day interval.

What If Your Cycle Is Shorter Or Longer Than 28 Days?
Ovulation doesn’t always happen on the same day, and the menstrual cycle can last anywhere from 21 to 35 days.
Just 10% of women ovulate precisely 14 days prior to their next period, and only approximately 30% of women have their reproductive window between days 10 and 17 of their cycle.
A number of factors may affect the timing of ovulation, including stress, nutrition, PCOS, and irregular cycles during puberty.
You can more accurately estimate your fertility window by monitoring your cycle around the halfway point or by employing ovulation tracking techniques like tracking your changes in basal body temperature, ovulation calculators, or fertility monitors.

So When Is Pregnancy Most Likely?
Pregnancy is most likely during the fertility window. After ovulation, sperm can exist in the body for up to five days, while eggs only last for roughly twenty-four hours.
You can become pregnant if you have sex:
- 4-5 days prior to ovulation
- On the day of Ovulation
- Day after the Ovulation
What is a Fertility Window?
Your fertility window is the time of your menstrual cycle when you have the best chance of getting pregnant.
Midway through your cycle, you reach your fertile window.
Your fertile window’s duration and timing can be affected by the length of your menstrual cycle. This window is typically defined as the three days before, coinciding with, and following ovulation.
You can determine the best time to have sex if you’re trying to conceive by calculating your monthly fertility window.
Bottom Line:
To maximize your fertility and get pregnant, follow and adopt a few lifestyle changes like avoiding smoking, limiting alcohol intake, having a healthy diet, reducing stress, and maintaining a moderate weight.
