I am nearing my menstruation and expecting to have it in a day or two. I am already having cramps and i am nauseous . Me and my boyfriend became sensual after a fight and without condoms he inserted his penis into my opening. Before his penis could fully enter into mine, he was able to withdraw it. will i get pregnant even if there was no ejaculation or penetration? Or how how big is the possibility that i could be pregnant? is there any chance that i'd get pregnant even after i have menstruation (if ever)? thanks
