I'm in a relationship and were sexually active but we never use condoms and he cums inside of me almost everytime. I am on birth control but lately I've noticed irregularities with my discharge and my boobs have been really sensitive and have gotten at least a few cup sizes bigger. I'm on my period but it doesn't seem anywhere near as heavy as it usually is and I've heard that it's rare but you can bleed throughout the whole pregnancy. I'm not really sure what to think. I took a pregnancy test back in October and is said I wasn't pregnant but I have had sex since then. Please help!
