OK I'm on birth control and my boyfriend and I do have sex quite a lot. Sometimes with a condomn and sometimes without. I usually get my period at the end of each month to the beginning of each month. I never really got my period from the end of February to the beginning of march like I was supposed to. I've just been having a lot of dark colored discharge. I've also gained an unusual amount of weight recently. I don't know am I pregnant?

Its 50/50, no one can tell you if your pregnant or not on the internet, take a test, you need mutiple amounts of contraception in order to prevent pregnancy, nothing is 100%
