Never, once we were TTC I stopped drinking
I haven't really wanted any to be honest I'm not much of a drinker anyway, so not drinking during pregnancy is nothing major for me. I usually only have a drink or two per year, usually around Christmas which was right around the time of conception. I didn't find out till early Feb, so I haven't had a drink since I knew I was pregnant .
I have one or two wines twice a week from the 2nd trimester. My OB says it's no problem, it relaxes me and I enjoy it. I never feel ****ed and eat whilst i drink many people in Europe (mainly France and Italy) drink during pregnancy as it's just a normal part of eating together. I think everything in moderation is ok.
