I didn't take any herbs during the IVF cycles. Only in the cycles in between IVF. I wouldn't want to risk taking any during IVF as they could interfere with the meds or do other nasty things.

I did make some diet changes leading up to each BFP (mostly reducing/eliminating dairy and sugar), but I've also heard other women swear by the endo diet.

Hopefully you won't have much longer to wait.
