Lady, that is really frustrating, that they won't advise you / take the lead on how to stim! It is interesting, the different methods! I didn't have to take BCP nor did I down-regulate for any of the cycle - it was the aggressive protocol each time (just once I changed doctors at the clinic, trying different combinations and protocols).
If your clinic has and uses an embryoscope, then I would definitely recommend that. Our fertilisation results were always amazingly good (considering DH's sperm, lack thereof / quality of), but the embryo development was not that great ... once using the embryoscope it definitely improved.
I think you need to discuss pros and cons with your RE, get them to advise which protocol would be best - it shouldn't be you telling them, they are the experts ...
Being no expert myself, of course I cannot judge how your eggs are, but I know that the doctor started thinking (being not the youngest any more) that my egg quality might not be that great any more (I did respond well the meds - too well at times, with OHSS). I started taking a high dose of CoQ10 (from NOW, maximum strength, 600mg), Resveratrol (both suggested by my doctor) - both improve cell-regeneration. In parallel, I am taking Zinc; get your vitamin D levels checked and also your thyroid. My thyroid levels were perfect for a healthy woman (at 2,1 or thereabout, sometimes 1,7) - specialists said, that when trying to conceive, a TSH level of around 1 or below is better, so my TSH levels have been artificially adjusted...
So maybe there are a few things you can do, to try and improve things at your end. Taking the supplements for a couple of months might be a good idea?
Anyway, a combination of taking everything, plus the varied stim plans, plus the additional shots + embryoscope ... it took several tries, but we got there (I still can't believe it, despite Pünktchen moving around to let me know he's there) - and I really am praying that Jo, Dovkav and I can bring some good luck to this thread and spread heaps of
