Backward tilt. A retroverted uterus is one that's tilted towards your back, rather than your abdomen; it occurs in 20% of women and does not have symptoms, RARELY associated with discomfort. It can't be prevented and there's no need to treat b/c it won't affect your fertility/ability to continue a pregnancy/have a vaginal delivery. It can only be a problem if caused by past surgeries/endometriosis, otherwise OK.
