Hi

I didnt have sex with my partner but he did rub his penis on my clit. And he didnt ejaculate at all. but i am worried i could be pregnant with pre cum even though he didnt go inside of me. the next day i got my period i now it was my period because it was heavy but 48 hours after i took the emergency contraceptiom and the next day my period stopped is this normal? My period lasted for two days
