Pcos and pain after sex. Help?

Hail
I have pcos and it seems like every few months I'll get pain after sex for hours. It's like there s alot of pressure in my lower stomach. I've been going through different websites trying to see if there s anything to help, and haven't found anything at all. The pain sometimes just shows up in the mornings or at night. I'm just really sick of being in pain all the time. If you know of anything that'll help let me know. Thank you
