helppppp!!!!!

So, recently my vagina has been off... my boyfriend and I have unprotected sex and he just pulls out. But my discharge hasn't been smelling the same recently. I just got off of my period and my vagina now smells odd. I can smell it through my pants and it makes me super self conscious. Im not sure if its because im sweating or not showering twice a day like i used to, or maybe the wash i use down there... any opinion is helpful!
