Can You Get Pregnant on Your Period?

Mar 7, 2025 | Sexual Health, Women's Health

Any time you have unprotected sex, there's a possibility you could get pregnant, including on your period. Although it's very rare, it can happen.

If it does happen, it's important to know your next steps. Keep reading to find out more!

 

Can You Get Pregnant on Your Period?

Yes. Although unlikely, it is possible to get pregnant on your period.

A typical menstrual cycle lasts about 28 days from the start of your period until the start of your next period. Your period begins the cycle, and ovulation (when the ovary releases an egg for fertilization) usually occurs in the middle, around day 14. So, a week or two after your period ends, you ovulate. Around that time, you are more likely to get pregnant.[1]

However, most women have variability in their monthly cycles. This means that every woman ovulates at a slightly different time, with some women possibly ovulating closer to their periods.

Plus, after the egg is released, it remains in the body for up to 24 hours. But after sex, sperm can last in a woman's body for up to five days.[2] So, sex around the time of your period could still lead to a pregnancy.

Three factors increase the likelihood of getting pregnant during your period:

  • Shorter Menstrual Cycles. You could ovulate a day or two after your period ends.
  • Extended Period (Duration of Bleeding). You could ovulate shortly after the end of your bleeding.
  • Mid-cycle Spotting (Light Bleeding). Your spotting mid-cycle could be a sign of ovulation rather than a period.

Even if you have regular cycles, it may be hard to know when you ovulate. According to one study, only 30% could predict when they were fertile.[3] So, even without these factors, it's possible to still become pregnant during your period.

Can You Get Pregnant Right After Your Period?

Yes, it's possible to get pregnant right after your period, especially if you have a short menstrual cycle or an extended period.

 

Can You Get Pregnant Right Before Your Period?

It's unlikely to get pregnant right before your period because the lining of your uterus is not ready for a fertilized egg. But since sperm can last in the reproductive tract for up to five days, sex right before your period could still lead to pregnancy.

 

What Does a Shorter Period Mean?

Women can bleed between three to seven days when on their periods. Factors such as stress, medications, illness, hormonal changes, or lifestyle changes can impact your period.[4] If you've missed a period, you should first rule out pregnancy by taking a pregnancy test. If the test is positive, your next step is to receive an ultrasound.

 

How Far Along Am I?

Home pregnancy tests can only detect HCG in your urine. They cannot tell you how far along you are or if the pregnancy is viable. The most reliable way to figure that out is to receive an ultrasound.

Call (256) 740-0640 to see if you qualify for an ultrasound.

 

When Do Pregnancy Symptoms Begin?

Women typically develop pregnancy symptoms two weeks after conception. Symptoms include a missed period, tender breasts, tiredness, and nausea.

 

How Soon Can I Take a Pregnancy Test?

You can take a pregnancy test as soon as you've missed your period. Positive home pregnancy test results occur about eleven days after conception (when the sperm fertilizes the egg). If you're concerned that you may be pregnant, call Shoals Women's Clinic to speak with our qualified medical staff.
