I am taking birth control regularly now for almost 5 months. My boyfriend and I have sex regularly and we don't use condoms and he pulls out each the time, never once has he came in me. 3 days ago we had sex but yesterday and the day before I was spotting. Today it stopped but I'm constantly discharging a thick watery/white liquid. I've read that it could be a sign of pregnancy but I know I can't get pregnant in 3 days. Could it have been from a previous time?
