Letrozole and alcohol???

I’ll be starting my first IUI this month. I go for bloodwork tomorrow and will be starting letrozole. I am going to a wedding this weekend, and I’m a bridesmaid. I’m not planning on getting out of control, but is it an issue to have a few drinks while taking letrozole? I know we’re going to have mimosas while getting ready, and I usually like to have a glass of wine or two during the wedding. I plan to speak to my doctor about it tomorrow when I go for my bloodwork, but I wanted to get some opinions and experiences from you all as well. Thanks!
