Bleeding and weird smell?

Ive been having this weird smell come out from down there, its like a smell of a vag when you dont wash it for a while but i wash it every few hours with water. my boyfriend wasnt around for two weeks so i didnt have any sex but when he did come home it hurt when he put it in as in a piercing pain on my cervix. i pulled through though but after we had sex i started to bleed. this was two days ago, im still bleeding up to now. the smell seems to have gone away but im left with a confusing bleeding vag. anyone know whats happening to me?
