Help!!!

Hi ladies. So a few days ago I thought I had gotten a uti. I'm very itchy and it burns down there and I've been peeing a lot. Yesterday I started spotting and my blood is like mixed with discharge and is like the consistency of discharge. I thought it was a uti but now my vagina has a weird smell and it's not getting better. Possible yeast infection? I don't think it's an STD my boyfriend and I both get tested. Help me ):
