I had sex at the start of October and had my period right after when I'm supposed to (at the start of every month), and it was protected sex, we always check if the condom is broken or not and it wasn't. My boyfriend also pulls out before he cums. I've recently had to start taking this medicine because I have something on my leg and the doctors did say I would experience a yeast infection but I've been having brown custardy discharge for a couple days now and today it was liquid.. I don't wanna think pregnancy but I'm leaning towards yeast infection because I have been itchy but I don't really understand the brown discharge ... please help
