So me an my bf have unprotected sex alot, an i know thats not smart but i really beed some anwsers right now. For the past few weeks i have been having cramping in my lower stomach, kind of like pinching, an white milky discharge, tender swollen breasts that are heavy an hurt really badd, i have hot flashes, i feel nauseous all the time but i havent vomited yet, an i am constantly wanting to eat, but certain smells make me want to vomit, an my period is 3 days late. Are these possible signs of pregnancy.?
