Yep, I had a very slow response to Gonal-f initially.

We were doing IVF so our dose started at 150iu, after 7 days estrogen was low (didn't get the exact figure) so my dose was increased to 300iu and 5 days later estrogen shot up to 6,000.

By the time we went to epu a few days later estrogen was around 10,000 (my Gonal-f dose was decreased again at some point before epu, but I can't remember exact days or doses now).

On u/sound we had 7 good sized follies but collected 14 eggs, all of which fertilized.

It can turn around really quickly once they get the dose right for you - good luck!!
