I have been having unprotected sex with my fiance, he would pull out when he was about to climax, my period only stayed on 2 days, am i pregnant?

Pregnant?: Are you ready to have children? Unprotected sex can lead to pregnancy. Sperm is present before the man climaxes, so the "pull out" method is not reliable at all. Sometimes implantation bleeding can be mistaken for a period. You could check a pregnancy test.

Unlikely: But it is safer to use contraceptive if u don't want to be pregnant , since some saman can escape before ejaculation.
