i had unprotected sex about four or five days ago and lately i’ve been feeling nauseous and cramping. it was right after i got off my period. but i also have some other facotrs that could cause this. me and my boyfriend are on a break and i stopped eating for two days until he told me i needed to start again so i began eating and lately i’ve been felling really nauseous and stressed being that i have final exams. also my poop has not been normal (i know tmi) but i’m concerned i’m pregnant help please
