lower abdominal pain

This is kind of a way to figure out what sounds more likely to be the problem, I’ve been having sharp pains where I’d usually get cramps, I jolt every time I sit down because of the pain and I’ve been doing some research and there’s a bunch of different causes, I did have sex today and it was in a awkward reverse position, but when I got home and went to the toilet i realised alone with my normal discharge I had little clumpy bits as well. but ontop of that I did quite awhile back have cysts form on the inside of my vagina. At the moment I’m taking the advice for the yeast infection taking a probiotic and going to bed with no underwear to air everything out
