Okay so i'll give you the full story before the question:
A few weeks ago my boyfriend and i were fooling around and when he came it got on me so he wiped it off with his fingers then wiped his hands onto a kleenex. A few minutes later he started to finger me, and now i've missed my period. I've also been on three types of anti-biotics for a head cold and throat infection for about 2-3 weeks, so i was just wondering if i should go to the doctor and have a pregnancy test run or if it's just the medicine throwing my cycle out of whack?
