newbeginnings284 - I did the GH and am now 10 wks. That being said, it was our first IVF with Warren (I swapped FS after x3 failed IVF's elsewhere) we were prepared to throw everything at our first attempt with Warren, every test, meds, vitamin, lipoidal flush, scratch, "special instructions" that Waz requested, we did (except the brandy at FET - that was the only thing I flatly refused). It's hard to say if it did contribute given we seriously tried everything for this one. I'm hoping that the combination of it all did it for me, plus I'm not sure how much or little of it was a placebo effect mentally cos I knew I was on an extremely better IVF plan from where I last came from! Sorry, that doesn't entirely answer your question, but I do know where it's possible, Warren does recommend it. If it is something you can do for a first go, I'd suggest you try it and see if it has a positive effect on you.
