Hi i was dianosed with polystic ovarian diease (which means i am not regular i onli get my period if im lucky every 3-4 months) well i noticed my breast have enlarged from a D to a DD and well i have been cramping and a bit of mood swings to i bought a pregancy test last night and it came out negative but this morning when i woke up i had a blood clot when i went to the bathroom ( no blood only blood clot) is it possible i was pregnant with a false negative or is it normal to clot with out blood?
