Obgyn

Any obgyns near hermitage pa?! I have one but all I've been asking from them is a ultrasound to make sure Im even able to have children... And my obgyn doesn't see a need Im doing a ultrasound. Endometriosis runs in my family And I just want to get checked for it... What do I do ?! I've been trying to conceive  for a while and no luck....so that's why Im so scared, and wanting a ultrasound !!!
