Hi, im 20 years old & ive been on the pill since like 14 & go through stages of being sexually active, like if im seeing someone or got a boyfriend.. Every now & then if i skip my pill my period starts, i could feel my period coming the other day there was blood but not enough to wear a pad or tampon, last night i had intercourse with my partner i hadnt had intercourse for 3/4 weeks & i know if i dont do it for a while i become tight again, but last night for the first time there was so much blood it didnt last long but it wasnt a nice sight :( please help !
