First of all, welcome! I've found a great deal of support on this board and hope you will too.
As for the wine: I drank moderately right up to the night before my transfer (didn't ask for medical permission, though). I am now 8.5 weeks, and of course I don't drink now. I did notice that once I started the estrogen injections I would feel the alcohol a LOT more, and I would feel hung over after only a couple of glasses. So, you might take it easy. A little may go a long way.
