I got off birth control a little over 2 months ago and i haven't had my period since then. i have had unprotected sex since then but he did not cum?

Try protection: Do a home pregnancy test: if you are old enough to have an erect penis inside your vagina, you must understand that males do secrete "pre-cum" ( pre-ejaculate) which contains sperm cells- so YES, you can get pregnant: I would advise always using condoms PLUS BC pills, spermicidal foam, jelly, or vaginal inserts. Time to take responsibility.
