What is wrong with my vagina?

Sophie

So I recently started the pill and me and my boyfriend had raw sex for the first time a couple days into it. Since then my vagina hasn’t been the same. I went through cystitis symptoms however I then noticed an unpleasant oder. I went back to my gp and had a urine sample and blood tests done but my blood testes only picked up a b12 deficiency. I haven’t had my urine results back yet, however recently my vagina ha started getting better, then this afternoon I try inserting a at home vagina infection testing kit and when I inserted it it really hurt, like a popping through my skin sensation and started bleeding. Then I wanted to see if I was able to have sex again so I tried with my dildo and it didn’t hurt or anything but when I would insert it, it jus made me need to pee and I couldn’t even hold it so I accidentally peed. I’m now in the bath and it still hurts to pee a little. What could this be and what should I do? Please help.
