That is really strange that you had AF 7 days after hcg shot.
He should test your progesterone on or around cd21 to see if you ovulated. I would ask him what the plan is. Let him know you feel kind of in the dark about what is going on and just ask him to explain it.
Best of luck to you..
Have you done Clomid or any other meds besides your HCG shot? I always ovulated on my own but was still put on Clomid to help raise my prog. Have you done a lot of tests for infertility? I went through all the tests, did four months of Clomid, and I just finished one month of injectables with IUI. My RE says the next option after that is IVF.
