I have a tilted uterus. I also have 3 children and didn't find out until after one ( 1st or 2nd) of the was born.
No, it' doesn't go back, because it is still tilted, maybe even moreso. When I get my period, I have major back pains, no cramping in the front like when I was a teenager. Interesting, I thought.
Never thought of lying on my stomach, may try that next time!
