My boyfriend and i have been having protected sex for 2 weeks. recently, i found a bit of cum and i'm not sure if it's mine? should i be worried?

You found discharge?: If you are saying you use condoms, first off bravo! if after sex you found fluid in the vagina that looked like cum (sticky, white/yellow), and the condom did not break, then this was most likely your own lubricating fluids - females will produce a lot of lubricating fluids when sexually stimulated. Hope this addresses your question.

Protected health inf: Please don't provide protected health information (phi) such as your name on this website. As for your question, i'm not clear what you're getting at. Women don't usually produce "semen" as men do. Perhaps you were more lubricated than usual? Some do ejaculate but you'd know it was yours if you did. Regardless, make sure he wears condom each & every time. Go see your family doc if still concerned.
