Okay before I get lectures FYI I wouldn't care if I was pregnant or wasn't. Just want some advice and personal experience is all. My bf and I were having sex on Sunday without a condom (been together for 6 years) I'm 23 and I'm on birth control, but since last Wednesday I've been on amoxicillin because of an ear infection. I heard that it can make birth control ineffective. Anyways we had sex but he was only going to thrust a few times and then we were gonna take it in the shower, but when he pulled out he started coming or pre cuming so I said you might as well finish, so he stuck it back in (after just wiping it off) and then pulled out again to ***. Anyways could I still get pregnant even tho I was on bc but antibiotics too or is it not a good chance? Also my cycle says that I should of started ovulating on the 7th until the 13th and my last period started on June 26th.
