Someone told me that a girl can only get pregnant for a certain number of days a month. Is this true? How long after your last period can you get pregnant? Can someone explain this to me? Thanks

Here's a fertility calculator you can use to see when you're most likely to be fertile:
In order for you to get pregnant, you must have a thick, blood-rich uterine lining (which is very thin right after your period), a mature egg which has been released from your ovary, which usually happens about 14 days after the start of your previous period, and live, vigorous sperm. The sperm can survive in your uterus for a few days, waiting for the egg to be released, so you should know that you can get pregnant even if you don't have sex after you've ovulated. There's no "on-off" switch for fertility. It's something that goes from not fertile to a tiny bit fertile, and increases gradually up to very fertile. Since each human body is different, there's no way to know for sure when you will be fertile. There could be a hormone mix-up and your ovary could ripen and release two eggs in one month. That results in fraternal twins. There could also be a problem where your uterus doesn't have the right nutrients to grow a baby, so you could be unable to get pregnant even though you have ovulated.
Anyway, if you don't want to get pregnant, use birth control every time (two forms are even better!) or remain abstinent. You can't count on your body to be reliable if there's so much at stake.
during ovulation, you are less likely to be pregnant. about half of 28... so about 14 days after your last period. (approximately) [ orphans's advice column | Ask orphans A Question ]
