20-30% of women have a tilted uterus and I am one of them. I read that the tilted uterus moves to the middle/forward position sometime between 10-13 weeks of pregnancy. I am 10 weeks and wondering what to expect.
In case anyone else is thinking about this, there are some exercises to help it: http://www.livestrong.com/article/468983-exercises-for-a-retroverted-uterus/
and your doctor can help push it to middle if it ever causes problems. Apparently, it can put pressure on the urethra and make it hard to empty your bladder if it does not move forward soon enough. ...though, you could put your chest to your knees while peeing if this is a problem.
