Getting pregnant is related to ovulation. Ovulation is the release of an egg from the ovaries. It is the time when a girl is most likely to get pregnant.

The answer is - Yes! Any time a girl has unprotected sex, she could get pregnant. A girl with irregular periods usually still ovulates, just not on a regular, predictable schedule. All girls, especially girls with irregular periods, can ovulate at different points from cycle to cycle. That makes it impossible for a girl to know when she is most fertile. Irregular periods also can make it hard for a girl to know if she is pregnant, since she doesn't know when to expect her period.

Having unprotected sex at any time is risky. Along with the risk of getting pregnant. If you’re sexually active and not using contraception, it’s important to consider the possibility of pregnancy and consult a healthcare professional for advice.
