Sandy. I agree with the other girls. You will get much better treatment with the RE. I kept pushing my OB/GYN to investigate my IF issues and she kept telling me to wait. She finally referred me to an RE after she got sick of listening to me. She suggested putting me on clomid-but I insisted on going to an RE instead. Those OB/GYNs seem to just be clomid pushers.
The RE may ask for another SA and the results from your HSG and ultrasound. They will probably do bloodwork to check for STDs and hormone levels and they should do day 21 bloodwork to check your progesterone to make sure you are ovulating. My RE did and internal exam and found some tenderness on my uterus. He suspected endometriosis and I just had a lap (laproscopic surgery) to diagnose and treat it. Not everyone has a lap. Only if your RE suspects endo. I had none of the classic symptoms and was completely shocked to find out that I had it!
I go to my OB/GYN in a few weeks for my annual. I'm really looking forward to telling her about the endo. She kept telling me I was fine and to just keep trying. Ha! I'll show her. Good luck and keep us posted.
