So I am on bc pills. My period is more than 10 days late. My period does this most of the time since I’ve been on birth control. I’ve took pregnancy test in the past and it always came back negative. So this time I have a feeling I could be pregnant. Something is telling me to take a pregnancy test. I don’t want to because they always came back negative in the past and I don’t want to waste money on an expensive pregnancy test. My nipples are sore and they look a little bigger, I’m a little nauseous too. But I’ve had this feeling before but I wasn’t pregnant.
