30. Health Myth: You can’t get pregnant during your period.
It is not very likely that you will get pregnant during your period. However, it can and has happened, so it would be unfair to say that you can’t. Specific scenarios make it more likely that you can get pregnant while on your period. If you are at the end of your period, say day seven or day eight, if you have an extended period, then there is a chance of getting pregnant. Sperm can live in your vagina for up to 6 days, and ovulation occurs in the middle of your cycle. If you have a short cycle, for example, 20 days, then pregnancy can happen.
If you have sex on the first day of your period, the chances of getting pregnant are very low. Many women have 28-day cycles, which is the average length of a menstrual cycle. When you look at the days when ovulation occurs, around day 14, then you are usually in the clear if you have unprotected sex near the beginning of your period. If you are concerned about getting pregnant, it is best to take all the necessary precautions to avoid pregnancy. That includes using condoms, oral contraceptives, or spermicides. Remember, some of these methods do not protect against STDs.
