i started minastrin birth control 2 days after my period came. ive been taking it for 2 weeks exactly now. after 7 days me and my boyfriend had unprotected sex the 8th day and have been maybe every other day. the past 4 days ive been having some cramps and here and there feel nauseous throughout the day. is it possible im pregnant or is this just known as a side effect when you start birth control?
