My boyfriend slipped his penis inside for a couple of seconds and he precame I know you can get pregnant from pre-cum but are the chances high Its two weeks before my period?

No it isn't especially high..........BUT it can happen. so be more careful in the future young lady!!!!

Answer:There is no sperm in precum. The way that people get pregnant from precum is that when the precum comes out, it flushes out the penis. If there is any residue from previous masturbation or sex, then the sperm will come out with the precum, therefor containing sperm. Precum and peeing will clear the shaft of any sperm. The sperm, however, can live up to 3 days.

The only way to know is to ask him if he masturbated beforehand or if he had sex beforehand without going to the bathroom before he had sex with you.
