How likely is it that I'm pregnant?

Alrighty, so basically I may be in a bit of a predicament. You're most fertile the two weeks after your period correct? Well in that two weeks I was on 900mg of penicillin a day. I'm on Marvelon for birth control but I was told that penicillin can affect it. I've been eating a lot, having trouble sleeping, my boobs hurt and they're veiny, and I started lightly bleeding today. I don't go off the pill until Monday for that one week where my period comes. Generally I'm off of it on Monday and it comes by Wednesday. I'm taking my pills like I'm supposed to, same time and every day. Is it early period or pregnancy do you think? Thanks alot.

I suggest you wait till Monday when you go on the placebo pills, if the bleeding gets heavier then, then it looks like your period started earlier (most likely an affect from the penicillin). If your period doesnt come, take a pregnancy test.

I assume this means you had sex during this time? Was it just one occasion, and did you use extra protection like a condom since you knew that the penicillin would affect your regular contraception?
Just take that into account, but really you will have to wait untill monday/wednesday

it could be early period,pregnant or even a infection.Try going to near by clinic to make sure everything is ok.Good Luck!
