hi, I am 42 years old and my transvaginal sonogram showed that I have an anteverted non gravid bulky uterus with two intramural fibroids in the fundal region, what does it mean to have a bulky uterus, I have been having clotty, painful periods. I have also been having pelvic pain after my periods with extreme low back pain for the last three months, the back pain intensified over the last one month. My menses last month were also extremely painful for the entire three days, very clotty as well and dark blood. I am currently on betapyn and celebrex but still experiencing the abdominal and back pain. What does this mean?
