I totally forgot what Lupron does to a cycle... (I must have my first failed IVF cycle completely blocked from my mind...LOL)
Now that I'm remembering things, what Mrs. A says sounds right...
I know that some REs give the lead follicle some room - i.e. 17MM / 18 MM / 20 MM
If you're not happy with this cycle, convert it to IUI or BD like crazy, you never know - it just might work out...
Make sure you get the trigger shot, though.
