My duaghter hasn't had a period since Dec. 2010 (not pregnant and labs are normal) and the doctor has put her on hormones to make her bleed and she has not. My daughter is having a transvaginal ultra sound next month. The docotr wants to look at all of her pelvic parts, she said something about her cervix detatching from the uterus what could cause this and what else could they be looking for
