It�s possible to get pregnant anytime you have vaginal sex, whether it�s the first or the 100th time. Even if a girl has not gotten her period yet, it�s possible that she�s about to start having it, and if this is the case, she has ovulated. When an egg and sperm are present, pregnancy is possible. It�s important to remember that pregnancy isn�t the only thing a couple has to be concerned about. If they do not use condoms, there is a risk for STDs.
If a girl misses her period does that mean she is pregnant?
No.� When girls first start having periods they often have irregular cycles and may even skip a month from time to time.� However, if a girl has had sexual intercourse and she misses her period, she could be pregnant. Getting tested at a clinic or doctor�s office is the only sure way of knowing.
