Suggest Treatment For Pain In Vagina And Abdomen After Having Sex

Hi I was having pain on my left side. Thinking there was a cyst or something there. So I had sex with my bf to see if it hurt during sex. It hurt in certain positions on the left side and hurt depending on how far he went in. It started to hurt so he stopped. I got up and all the pain was gone fron my left side and moved to my lower abdomen and my stomach was rock hard and so swollen. It hurt all night and all day today.
