Can You Get Pregnant on Your Period?

can you get pregnant on your period?

Getting pregnant requires having sex during the fertile window of your menstrual cycle. But can you get pregnant on your period, or is that “safe” time? Let’s explore the chances and factors involved.

Can You Get Pregnant During Your Period?

The chances of getting pregnant during your actual period are very low. Menstrual flow happens because no embryo is implanted in the uterus, signaling that ovulation has passed.

However, sperm can survive 3-5 days inside the body. So if you ovulate shortly after your period, the sperm could still be waiting to fertilize the released egg.

What Affects the Chances?

Several factors impact your odds of conceiving during menstruation:

  • Menstrual Cycle Length: Those with shorter cycles ovulate sooner after their period.
  • Ovulation Timing: Irregular cycles make pinpointing ovulation difficult.
  • Sperm Viability: Sperm survive days after sex, remaining ready to fertilize.

The only sure way to avoid pregnancy is abstinence or birth control. Even on your period, you could conceive.

Can You Get Pregnant Right Before or After Your Period?

You’re most fertile right before and after menstruation. Here’s why:

  • Before: Sperm can live up to 5 days. If you have sex on day 23 of a 28-day cycle and ovulate on day 14, sperm could still be waiting.
  • After: Some people ovulate very early or have short cycles. If you have sex on day 4 and ovulate on day 7, sperm could still be present.

The days right before and after your period bring the highest chances of conception.

Ovulation and Other Considerations

Ovulation day varies, even if you have regular cycles. Here are some other factors:

  • Irregular Ovulation: Perimenopause, breastfeeding, etc. can impact ovulation timing.
  • Spotting: Light bleeding around ovulation may be mistaken for a period.
  • Birth Control: Some methods lighten periods or eliminate them.
  • Short Cycles: People with short cycles ovulate closer to their periods.

The bottom line? You could get pregnant from sex during menstruation, but your odds are lowest at that time. Use protection if pregnancy is not desired.

According to the American Pregnancy Association, the chances of getting pregnant during your period are as follows:

Day of Menstrual Cycle Chance of Getting Pregnant
1-5 Low
6-10 Moderate
11-14 High
15-19 Very High
20-24 High
25-28 Moderate
29-31 Low

The Takeaway

While you can conceive during your period, the chances are slimmer than at other times in your cycle. But the only surefire way to prevent pregnancy is abstinence or contraception.

For the highest odds of conception, focus intercourse on the days right before and after your period ends. But if you don’t want to get pregnant, use protection no matter where you are in your cycle.
