Vagina burns and blood

Hello and thank you for taking your time to read my post..

I was sleeping and I felt burning inside the vagina which also makes me feel like i have to pee but if i actually go to the bathroom i can barely peee.. and when I pee I feel the pain and clear blood cones out.. Now i cannot go to sleep due to this pain and discomfort. By the way this is second time this week. I never had this problem and Im 21years old. I had intercourse last night and I did not feel any pain. Also. According to glow calender my period should start tmrw.

Please tell me how i can ease this pain and what might be causing the pain and pee with blood..

Thank yoy for your time
