Hi Marrybruce,
I had very similar feelings to you about 12-18months ago. It hurt to have sex and after several trips to different GPs it wasn't getting any better and worse still we were trying to have a baby. I ended up going to a Gyno and had a laparoscopy, where they found out I had endometriosis. It can make getting pregnant harder, but once you are pregnant, it does relieve the symptoms and improve the condition, so does the pill apparently. The Gyno recommended I go on fertility drugs, but I ended up getting pregnant with out them. I can't really give you any facts on it, as I am not very clued up on the whole thing, but I will try and answer any questions you have. Hope that helps a little.
