Had sex and now I've been bleeding for over a week

Tamia
So I had sex on the 1st (honestly wasn't really in the mood so it wasn't as wet down there as it usually is) because it was rushed which made it kind of roughnbut the next day I noticed I was bleeding heavily and was in slight pain. The pain has stopped but I'm still bleeding...I don't know know if this is due to my bc (nexplanon), a period or if something is really wrong because I still had sex although I wasn't in the mood. Yes we used a condom
