You can't get any more loosey goosey than C.ooper! LOL!
It's as they said - call once AF arrives. But make sure you have medication on hand before AF arrives because you want to be prepared. If your next question is "well what medication am I supposed to have if I don't even know protocol?!" then the answer is as loosey goosey as you can imagine - "anything".
Did you discuss specific meds with Dr. Ch.eck? If you don't recall take a look at your post-consult letter. He may have mentioned in there. Often it's just a matter of them going with whatever you have on hand or whatever your insurance covers. For stimming I'd have some Gonal F or Follistim on hand and also some Menopur. And then some ganirelix or Cetrotide.
