I also have a tilted uterus - no doc ever explained to me what it meant, the only info I've gotten is from here! One of the girls suggested laying on your stomach with your butt in the air after DTD, as opposed to laying on your back with pillows under your bum, as the cervix points the other way.

Apart from that, we've been TTC for 3 1/2 years, so I'm probably not much help!
