Vagina smells like menstrual blood??

So I had unprotected sex Tuesday-Friday. We tried using a condom Wednesday but it was very uncomfortable. The next day (Thursday) I noticed when I peed my vagina smells like blood. My urethra is swollen just a little and when I pee it feels tender and like I constantly have to pee when I don’t. My period is suppose to come today but no blood. Can anyone help??

Also side note: two months ago we bought a condom from a gas station and used it & later the next day I found out that I got bv I’m thinking maybe I’m allergic ??
