Had sex 2days after my period ended I know I ovalated 6 days after sex could I be pregnant? But could I be pregnant. Help don't want to be.

Possible. While sperm can stay present for up to 7 days, most of them are dead or non motile. In addition, if you're using an app to determine ovulation its just a best guess. Never assume you ovulate on a specific day. I would check a pregnancy test about 14 days or so after unprotected sex and its probably time to get on birth control or at least use condoms.
