His and Her Health

Hello. Here's my question:

I've been experiencing weird sensations after fooling around with my partner the other day. I was at the very end of my period, had the menstrual cup in, but he slightly entered me (unprotected). Soon after (or during) I felt like I was chafing. In the morning, the sensation was still there, and seemed to kind of burn more. My discharge that morning was chunky, so I thought I was getting a yeast infection, but that went away immediately. My discharge since has seemed maybe a little more watery than normal, but it is a normal color (cloudy white) with no foul smell. Along with the burning I experienced nausea quite badly for 3-4 days, as well as cramping in my left side, around my ovary.

I was freaked out looking for symptoms and found that mine sound a lot like chlamydia or ovarian cysts. I've been tested for STD's before being with him, and he says he was also tested, so the likelihood of that is slim, but I do have a doctor's appointment next week. Could it be a cyst that ruptured? I have had pre-cancerous cells detected on my pap tests in the past. Could that have something to do with it? The only thing that seems to affect me now is still a little discomfort around my left ovary.

Thanks.
