YES! There is ALWAYS a chance you can get pregnant, ovulating has nothing to do with it. Unprotected sex is capable of pregnancy at any time, and STDs at any time. Just be careful. If you are looking to get pregnant, then unprotected sex is the way to go, if not then protection is needed..TRUST ME!!
The sperm can live for 5 to 7 days before it dies. So if you have sex before ovulation then it is the strong possibility that the sperm would meet egg and you will get pregnant.
If I had sex september 18 and ovulated the 24 could I be pregnant
