So sorry to hear about your failed IVF.
Yes, I did a failed IVF at Cooper in July. For that cycle, I did 150 Gonal F daily and then added Ganirelix at CD 7. I started that cycle with 4 antral follies, got 3 eggs, all of which fertilized and made it to transfer. We transferred all 3 embryos but none of them took unfortunately. BTW, the reason we did this protocol was that I had the drugs leftover from a failed IVF attempt at RMA in May - that cycle was a complete disaster. I started that cycle with 9 antral follies, only had one mature follicle after 11 days of stimming with 450 Gonal F daily. They cancelled my IVF cycle due to poor response and converted to IUI which was a BFN.
In contrast, for my successful cycle at Cooper in late Aug/early Sept, I did 150 Bravelle/150 Menopur daily with Cetrotide at CD 7. As I think I mentioned to you before, I also took Ubiquinol/ COQ10 for about 5 weeks prior to retrieval, and also added estrogen support (Vivelle patches) in addition the P4 support after retrieval. Starting with 5 antral follies, got 3 eggs, again all of which fertilized, but only 2 made it to transfer and one of them I am almost 26 weeks preggo with
To answer your question, I skipped a month in between all of my IVF attempts, to allow my body and sanity a few weeks rest in between attempts.
Hope that answers your questions - let me know if you want to know anything else! Good luck deciding your next steps - I know it is really tough, esp. after a disappointing result. Hang in there!
