I feel for you because I think it would be TOUGH to be a "treatment novice" at C.ooper. Since I have done a lot of treatments elsewhere including 2 IVF's I know the lingo and what to ask. Without that knowledge, I think it would be very hard and I wish I could make it easier for you.
I don't know why you aren't supposed to BD until you get a positive. No ideas on that if DH is fine.
Drugs: your insurance may prefer one brand over another and that will dictate which one you should use. Follistim and Gonal F are the "same" thing and are gonadatrophins. Menopur is also a stim and is half LH and half FSH. Cetrotide and ganirelix are the "same" but different brands that will prevent premature O(brings the LH down). These are used when you need to slow down a big follie to give smaller ones time to catch up. Maybe this will help a little:
