Please help

So my and my boyfriend have been together for a month and the first time we had sex it smelt, like blood almost, ever since then i've been trying to avoid it but ever since we started sleeping together it's kinda smelt down there ( I shower twice a day now cause of it and it still smells), like all the time, some discharge during the day but then when we have decided it's almost like a dry blood rust color. Have any of you had somthing like this happen? If so what is it? & how do I fix it? I have absolutely no clue what is going on and I'm going to the doctor on Monday but if reall like some female input and ideas before. Can any of you lady help me out?
