I've been on birth control pills for about 10 months. My fiancé and I have been having sex quite a bit this month without a condom but he never finishes inside me. I should have gotten my period on Saturday or yesterday and its still not here yet, its usually right on time so that's why its kind of worrying me. It has been a stressful month. I've been having bad cramps, upset stomach and having to pee a lot and my boobs are hurting bad. Its probably nothing but just curious if anyone has missed their period on birth control pills and weren't pregnant? Thanks
