I began taking the birth control for about 2 weeks and had protected sex. At one point my partner then took off his condom began rubbing himself then placed his fingers with cum if I'm not mistaken inside me. It's around the time that I get my period and haven't had it. I am stressing out about there being a possibility that i'm pregant and for some reason tend to see myself getting fat & I'm not sure if it's my imagination or not. I heard that once you start taking birth control you might not get your period, and I'm confused if I am pregnant or not. Please help.
