Can you get pregnant during your period?

The topic of period sex is a diverse one. For most people, it’s a no-no, but it’s a normal part of sex lives for others.

So our goal today is to answer the question: “Can you get pregnant on your period?”

Can you be fertile on your period?

The answer to this question is yes, even though it’s extremely unlikely. It’s highly unlikely for women to conceive when on their period. But given that the sperm lives in the female reproductive system for up to five days, a small percentage of women can become pregnant when they have unprotected sex during their period. It sounds simple right?

For example, if your menstrual cycle is usually shorter than 28 days and you have sex before the end of the six-day-long period and shortly after you ovulate, then there is a slight chance that the sperm will survive, and you may end up getting pregnant. So even though getting pregnant on your period is highly unlikely, it is still possible, especially if you don’t know your fertile window.

Can you ovulate on your period?

No, you cannot ovulate when you are on your period. There are extremely low chances of being fertile while on your period. So if you’re trying to conceive, the best time to plan for sexual intercourse is 24 hours before ovulation and on the day of ovulation. Note that there are women who experience spotting around the time of ovulation. Spotting is an indication that you may be fertile.

Chances of getting pregnant while on your period

It’s highly unlikely for you to get pregnant days before you receive your period. However, our cycles are not similar, and every woman is unique, which means our peak fertility varies. It means that some women are most fertile days before menstruation. Some women can become pregnant five days before their period, assuming they ovulate towards the end of their cycle. But in reality, fertility happens earlier in the menstrual cycle. Typically on days 14-15 of a 28-day cycle.

Can you get pregnant on your period with birth control?

Unfortunately, there is no specific birth control method that is 100% effective. If you are on your period and you happen to use a condom, and it breaks, and you’re fertile immediately after your period, there is still a chance that you may become pregnant even though it is extremely unlikely. But if you are using hormonal birth control and experience monthly bleeding, it may not be a period but what’s known as withdrawal bleeding. Hormonal birth control primarily functions by stopping ovulation, so don’t expect to have a fertile window the same way you would when using non-hormonal birth control. But when using a birth control method, it’s possible to know your fertile window.

The ins and outs of period sex

Now that you are aware that you can get pregnant while on your period, it’s vital to take the necessary precautions. Barrier methods like the condom are effective in preventing pregnancy and protecting against STI when used correctly.

Although most people think that having sex while on your period is gross or messy, it’s perfectly healthy, and most women agree with this for different reasons. Progesterone levels increase around menstruation, increasing your sex drive. In addition, orgasms reduce period cramps and cause more contraction of the uterus, which eventually may result in shorter periods.

Before you get into the heat of it, ensure you remove any menstrual cups or tampons before having sex. These are dangerous and can block the vaginal passage when left for a long time in the vagina or when they are misused.

You may be expecting to experience a Stephen King-style horror scene but instead end up surprised to find out that there is little menstrual blood. The heaviness of your period varies from one cycle to another. But the average woman during her entire period produces 2-3 tablespoons of blood only. With that said, it’s good to have an extra towel beforehand or have steamy sex in the shower.

Period tracking and logging sex

Women who use the Fertility2Family Basal thermometer every morning to record the temperature in an app such as Fertility Friend Ovulation App. The app works by identifying an increase in body temperature right before ovulation. It means that women who use Fertility Friend app can tell when they can or cannot get pregnant. So it’s possible to know your fertility while on your period or any other day during your menstrual cycle. In addition, you can use the app to determine where you are in your cycle and plan for your period and the right time to do a self-breast exam or PMS.

Your body undergoes two phases during your menstrual cycle, separated by your ovulation day. We will help you know the two phases by using your basal body temperature, which you will record in the app. The app predicts your upcoming ovulation depending on your historical data such as average ovulation length, cycle, day, etc. The app recognizes that each cycle is unique, and ovulation may not occur the same day as your previous cycles. When your basal body temperature is high enough, it will use the temperature to calculate your most likely ovulation day. 

Just remember, an app is built of algorithms and should not be used solely to predict your fertile window. We always recommend using a fertility awareness method to check your cervical mucus, cervix height and using ovulation tests and a basal thermometer together.


It’s possible to become pregnant when you have sex during your period due to various reasons. Bleeding from ovulation can occur, and some women confuse this with their period. When you have sex during this time, it’s possible to get pregnant. Also, if you have sex during the last day of your period and within the next few days after your period, you ovulate, the sperm will likely fertilize the egg, and you may end up pregnant. 

To protect yourself against unplanned pregnancy and STDs, ensure you use a condom every time you have sex. Couples could try using birth control methods such as pills or an IUD. Your doctor will advise you on the best form of birth control for you. But if you are trying to conceive, it’s best to use your cycle to determine when you will ovulate and plan for sexual intercourse around your fertile days.

So, whether you’re trying to conceive or not, tracking your cycle is of great importance. Fertility2Family ovulation tests will help you identify your most fertile days to help you know when you can easily conceive. Don’t follow the misconception that a woman can’t get pregnant when she’s on her period. Even though the odds of pregnancy are very low when you are on your period, they are not zero.
