Anyone out the with an Antiverted Uterus that has any tips?

Alycia
My DH and i have been TTC for 9 months. I found out recently that i have an antiverted uterus which can make it harder for the swimmers to make it where they need to. My OB said there is no proof behind the propping your bum up after BD but i have been tryong and still no luck. I feel like there has to be some other technique out there that worked for someone else?? HELP ME OUT HERE LADIES!! THANKS IN AFVANCE!
