uterine pain from diseases

A
I have uterine fibroids and endometriosis and I was wondering if anyone else had any real pain because of them and what you did to help alleviate the pain.
I get really bad pain after sex and orgasm, when I poop, and if I exercise. The only thing I've found that helps is sitting in the bathtub and running hot water on my belly and back. 
Also, if anyone has these diseases, was it hard to get pregnant and how long did it take? My husband and I just started trying and I'm a little anxious it'll take longer than I want.
