10th retrieval got us our baby who is now almost 2. It was a long road. No diagnosis. Tried Columbia, Shady Grove, and ended up moving overseas so the clinic that worked was overseas. Of the first 10, 1 was ag CFA (BFN), 4 at SG (all BFN), 1 overseas miscarriage, 1 overseas chemical, 1 overseas BFN, and 1 overseas BFP. I think whatever they did overseas was the right protocol for me and it speaks to the importance of trying different protocols, which might mean trying different doctors.
