I've always triggered with Ovridel or some type of hcg. My last RE was going to have me trigger twice in hopes of getting more mature eggs. He was going to have me trigger with a full dose, then a 1/2 dose 12 hrs later. He ended up not doing it for fear of my getting OHSS. Hopefully this new protocol does the trick when they don't have to worry as much about OHSS since that was their fear before.
IVF #1-cancelled d/t embryos arresting before transfer (3/09)
IVF #2-BFP 9wks-7/30/09 (6/09)
IVF #3-BFN (5/10)
Good luck with this third cycle! I hope the new protocol does the trick.
