Fibroids on Uterus

Anyone have experience with fibroids in their uterus? I was having severe pain on my right side. Went to the ER thinking it was my appendix. The U.S. Showed a fibroid on the right side of my uterus. Dr said they are common over 50% of women have them but don't know until they become pregnant and the fibroids grow and cause pain. I am nervous they are going to keep causing  pain and issues the next few months. The pain even gave me contractions. Anyone else deal with this?
