Im a virgin and yesterday me and my boyfriend was grinding naked but I was on the top and was rubbing on the penis shaft and not on the tip... there was precm but I was not in contact neither my vagina.. I came off on his penis and then he ejaculated but no where near my vagina.also he said that he had a ejaculation 3 4 days before.. I took the ecp pills (2) within 24 hours... is there any chance of pregnancy? Help me out.
