My husband and i r ttc. we had unprotected sex 5ds before my period. i started my period on the day it was suppose to start could i still be pregnant?

Unlikely, but: It's unlikely that you are pregnant, but there's always a chance if you're having unprotected intercourse. Usually the most fertile time is mid-cycle: about half way between the start of your last period and when you expect to start your next period. If your cycles are 28 days long, then that would be around 2 weeks before you period is expected. Best way to see if you're pregnant = test!
