Pain pain pain and discharge

So the other day I had sex and I woke up with swelling and a tiny amount of blood. I thought it was because we had sex for quite a long time that night. Then, two days after sex I started having this thick white discharge mixed with some blood and I was still swollen and it's slightly itchy and painful. Also when I pee it burns my lady parts and there's a little blood. I have a gynecologist appointment on Monday but Iid like to know yall's opinions first.
