While unlikely, unprotected sex during or right after a period can still cause an unintended pregnancy. Remember, sperm can live in the body for several days. It’s also possible that the bleeding could be mistaken for ovulation bleeding or spotting. A person is most likely to get pregnant when they have sex right before or during ovulation. If a person has irregular periods, it can make it harder to track ovulation. Play it safe and use a condom!」4月6日 5時29分
