Question your gyn on this... as there are surgerical options to "fix" a tilted uterus. Sometimes after pregnancy the ligaments holding the uterus in place stretch, or lose their tension during pregnancy and the uterus can become tipped or retroverted - and a dr can go in and "tighten" these ligaments and return the uterus to the correct position.
Its funny how some people do not understand the pain and discomforts that can be caused by a tipped uterus. My doctor mentioned mine just in passing, and never even mentioned it could be causing all my pain. I had to research this and have learned alot. I plan on going back to a DIFF doc.
Just think.. the uterus is tipped backwards towards the back of the pelvis, it would have to cause alot of pressure on the bowel and back as it is not the "normal" position that it was meant to be in.
If your gyn won't help... seek the advice of a different one, and a different one again if need be, until you find one who will listen.
"My dr doesn't seem to have a solution- she just says- they do that- as long as it doesn't stop you from day to day activites don't worry about it." I can't believe a female doctor said this to you - she obviously does not have much experience with this.
