My boyfriend and I had unprotected sex last May 10. (We used the pull out method but i inow it does not count as a contraceptive). I did not take the morning after pill because i did not anything about it because we din't have sex education in my country. I've had my period on May 22 and it lasted for 6 days..... Yesterday, june 23, I saw blood in my undies, it was like my period for the 1st day but it stopped today..... My breast also hurts..... Could I be pregnant?
