ohmy I have done two rounds of IVF ICSI, and I like my wine. The first round I was very good though not completely teetotal for two or three months before, as was other half (under my policing). It didn't work out. Then came Christmas and despite the fact that we would likely go again in the New Year, Christmas was a very boozy affair. I just didn't have it in me to be good. Round two was actually earlier then I expected in January, this was the one that worked I hope this helps. People put different stock by lifestyle changes and most say 3 months, so if you delay you will likely then think is a month enough? Don't make this your focus is my advice, there are so many factors for success and most out of our control and unclear. Good luck to you.
I've just had a lovely weekend in French wine country, enjoying the local produce . We are starting our second round of IVF as soon as my period comes (due about now!). I got a BFP from our first cycle (but miscarried) and had the odd glass throughout the process. It's enormously stressful. I think anything that relaxes you and makes you feel more "normal" while you are going through it is not detrimental. BTW, my mc had nothing to do with the fact that I had had the odd glass of wine, the embryo just didn't develop past a certain stage.
