Me and my bf had sex the night before my period he came on my stomach and no longer then 1 min i put the wet sperm in me with him knowing. and i prego?

Maybe. Maybe not.: Couples who have sex tend to make babies. That's how we humans are designed (so we don't go extinct). Anyway, a home urine pregnancy test gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.
