Check out my post below to The Same Boat...that said, I did a lot of googling and didn't see a lot of women who busted through the lupron. Maybe others just don't post, but anyhow.
Also, what they do is check your progesterone (bloods) and ultrasound (ovary follicles, AFAIK). They have you do those about 7 days after taking lupron.
I wonder if you can start taking lupron earlier in your cycle so that you have more runway if you're doing a shared cycle where dates are pretty much fixed (so get on the wagon or your embryos get frozen). They build in a few days padding, I think, in case your lining is behind, or your ovaries decide to be obnoxious. It did not even cross my mind that mine would actually be a factor in getting pregnant.
Thanks for your kind words. God, I hope there aren't so many more huge bumps in the road in front of me (or any of us). I feel superstitious for even saying that.
