I drank wine a couple nights before my successful transfer. We were having a dinner party and I just did not want to call attention to anything since I usually have a glass of wine. I did not want anyone to think I was already pregnant since I was very sensitive to that. I had a couple of glasses on a Saturday night and my FET was on Monday. I did 6 DE cycles (4 at a different clinic and 2 at SG) and had very moderate alcohol during 3-4 of them and no alcohol for the others. So I think a modest amount is fine.
As noted I am a SG grad - I did the shared risk cycle and got pregnant in the FET of my first shared cycle there. Glad you found this site -- there is great support here. GL
