Basically i have alot of cramps that feel like my cervix is spasming. Its sort of like period cramps but there's no bleeding and its pretty much everyday. Sex can also be really painful at times...it feels like the penis is hitting something (which I;ve assumed would be my cervix). I've been tested for STI's and had a smear and everthing else and they all came back clear. My GP has given up and i really don't know what else to do. Any ideas?
