So I was with a girl for 3 years, so there was obviously no way I could get pregnant but now I recently starting being involved with this guy and we had sex on the 7th. Yes we used a condom and he pulled out and checked it for leaks and there were none. I usually get my period the first week of every month and I just got it again today. It's not light like spotting but it's not overly heavy like most of my periods are. Please tell me I have nothing to worry about! Also I haven't had any symptoms or anything out of the ordinary.
