Sex on your period: Fact or Fiction?


Sex during periods. As a sexual health educator, I am asked about this subject a lot.

“Do other couples do it?” “How does it work?” “Will I get pregnant?”

There are some myths and half-truths floating around about sex during a period, so we are going to try to set the record straight…

Can you have sex on your period?

Yes. But like all issues surrounding sex, communication is critical. This means checking in with your partner. Depending on whether you’re the one menstruating or not, questions might include: “How do you feel during your period? Would you ever want to have sex while you’re menstruating?” or “I’m on my period right now. How do you feel about having sex while I’m menstruating?” For many folks who menstruate, sexual desire changes during different times of the menstrual cycle. For example, a person might experience increased desire during menstruation or ovulation – it all depends on the person. Be sure to talk about desires and feelings to ensure everyone is on the same page from the beginning.

Is having sex on your period bad for you?

No. Having sex while one or more partners are on their period is not harmful. In fact, there are a few ways in which it might be helpful! First, the contractions of orgasm might help relieve menstrual cramping. Second, sex might feel particularly great because the vagina can become super lubricated from menstrual secretions. If you or your partner worry about a mess from the blood, consider spreading out a towel or having sex in the shower to minimize post-coital cleaning.

Can I get pregnant if I have sex while on my period?

Yes. We get a lot of questions about specific situations on this – but the short answer is always “yes, it’s possible to get pregnant at any time during a menstrual cycle.” To put that in writing again – if you have unprotected vaginal/penile intercourse during your period, it is possible to get pregnant. This can happen if you have sex before, during or after your period.

You are most likely to get pregnant if you have sex around the time of ovulation. Ovulation is when an egg is released from the ovary, and it usually occurs about 14 days after the start of your last period. Many women have unpredictable ovulation or may have spotting at the time of ovulation, which could be confused with a period.

Plus, sperm can live in a vagina for up to five days. Yup, five days. So if an egg comes around at any point during that time, you could become pregnant.

If you have had penile-vaginal sex without contraception and you don’t want to get pregnant, consider Emergency Contraception (such as Plan B, ella, Plan B One Step or a Copper IUD). Many of these are available at most pharmacies over the counter and are pretty darn effective for up to 5 days after unprotected sex.

There are more reliable methods of contraception than Emergency Contraception. We encourage you to speak with your pharmacist or medical provider about contraception options that might work for you.

Are other people having sex on their period?

Based on the number of folks who are reading this blog article – yup. But really, it doesn’t matter if other folks are doing it or not. Having sex during menstruation is a personal decision, so we again emphasize that you should talk with your partner to see how they feel. If nothing else it can be another opportunity to get to know your partner and their likes, dislikes and comfort level.

    Hello, So my boyfriend and I been having sex for the past 4 days now and each time he nutted in me. Today Jan.4th, I’ve been having slight cramps and light bleeding. Really don’t feel like I’m on my period until I wipe and see the light blood. Usually I have heavy periods and intense cramping but not this time. Am I pregnant? What’s going on? Please help

      Typically even light blood would be an indication that you are not pregnant.

      Hi Shantel – in short, it’s possible, yes. It’s basically always possible to get pregnant. But if you’re diligent about tracking your cycles, you can find days to have sex that have a lower or higher likelihood of pregnancy than others. Hormonal or barrier birth control, however, is a much more reliable option if you don’t want to become pregnant right now.

      Hey Muneeba – it sounds like you’re saying you used a birth control pill for a month, got a period and at the end of that period had sex. If that’s the case, you are not likely to be pregnant due to your use of the pill. But if you don’t want to become pregnant, we encourage you to keep using the pill at the same time each day so that your chances remain low.

      Hi Michelle,
      Plan B can change your cycle, yes. So what you noticed is a typical response to Plan B. Hopefully you’ve started your next cycle at this point. However, if you are sexually active, please consider a more regular form of contraception than Plan B. There are lots of options that exist. Learn more at bedsider.org.

      Hi Kent – thanks for your question. You sound worried about the potential for pregnancy, so you might want to talk to your girlfriend and a medical provider about contraceptive options that are more reliable than the pull-out method. That being said – pulling out and having sex during her period both minimize your chances for pregnancy. Since it’s so close to the experience, you could also talk to your partner about emergency contraception, available over the counter at pharmacies. Hope that helps.

      Hi Jojit – there is no time of the month where a person with a uterus can have sex with a person with sperm and be 100% certain they won’t get pregnant. Again, this is because sperm can live for up to 5 days inside of a woman and ovulation (when an egg is released) varies. But – the least likely time to get pregnant is during a period of a person with regular menstrual cycles. So – most likely you’re not pregnant but yes, there is a chance. Hope that helps.

    Hey my boyfriend and I had unprotected vaginal and anal sex on the last day of my period. He came inside of me anally. Is Plan B necessary?

    • HealthyHeels June 22, 2017 / 1:00 pm

      Hi Tanya, anal sex cannot result in pregnancy. But the vaginal sex could due to pre-ejaculate which contains sperm. Pre-ejaculate has fewer sperm and having sex during a period reduces the chances of pregnancy. So your likelihood of pregnancy is small, but there is a chance. Since we are so slow in responding to you – it’s way too late for Plan B. Hopefully you spoke with your medical provider to find out more. Best of luck.

      Hi Suzaena,
      There is a chance of pregnancy due to something call pre-ejaculate. It’s a drop or two of semen that comes out prior to ejaculation and it does carry sperm.
      Three days after unprotected sex, it is unlikely to notice pregnancy related symptoms, but your anxiety around it (enough to write us a note with a “Pls ans me” at the end) indicates to us that finding a method of contraception might be worth it for your mental wellbeing. If you’re a UNC student, you can make an appointment at no charge to you to discuss options. You can also learn more at bedsider.org. Good luck!

      Hi Angel – it can definitely be stressful to notice changes in your cycle after unprotected sex – which is why using protection and/or birth control and be such a gift to everyone involved. Having any sort of bleeding after unprotected sex is usually an indication that you’re not pregnant. If you’re a UNC student, you can come speak to a provider at no charge to talk about contraceptive options and your specific situation. Hope that helps!

      Hi Jackie,
      Plan B is known for exactly this! Many women report sporadic bleeding for several weeks after taking Plan B. It’s likely nothing to worry about as long as you’re not having any pain – and the bleeding likely indicates that you’re not pregnant. Hope that helps!

    • HealthyHeels January 26, 2017 / 2:57 pm

      Hi Sakshi, The theme to all of our answers is the same with yours – yes, there’s a chance. But it’s small. If sex is between people who have eggs and a uterus (like you, it sounds like) and sperm in their bodies (like your bf, we’re assumign) and have the kind of sex where the sperm gets near where the eggs hang out (like penile / vaginal intercourse, for example), there is no time of the month where pregnancy absolutely cannot happen. But – from a timing perspective, if a woman has regular cycles, having sex while on her period is the least likely time of the month to conceive a child. But it’s not failsafe and each day from the beginning of the period most likely increases the chances of pregnancy, as the woman is likely getting closer to ovulation with each day. If you’re looking to reduce your chances, consider contraception options.

    Hello . I’m just wondering if I will get pregnant if we have intercourse on the last day of my period, I was surprised to see that I still have it the other day. Is it normal ? Am I still going to be pregnant and lastly is it okay to take a pill if I’m only 16 year’s old. I hope you answered it because I’m freaking out I don’t even know what to do. Thank you.

      Hi Wayne,
      If you have regular cycles (the same number of bleed days per month and the same number of days between bleeds), then most likely, having sex while on your period will not result in a pregnancy. But there IS still a chance.
      Yes, you can take the “morning after pill” to avoid pregnancy if you’d like. You should be able to pick it up at your local pharmacy without ID, and if you don’t want it to show on your parent’s insurance, you can pay for it yourself. The sooner you take the morning after pill, the less likely you will get pregnant.
      You might also want to speak to a medical provider about more effective birth control methods – like condoms, the pill, the patch, the ring, or an IUD.
      Hope that helps. Good luck!
