Thanks ladies :) I had myself one glass. And it felt nice!
A small glass should be okay. Go with what you are comfortable with. Some doctors encourage a glass or two every now and then, always in moderation and as long as you dont feel massive effects from it (your tolerance might be much much lower now), might as well enjoy yourself! :) In parts of Europe many women continue to enjoy a glass with dinner and everything is normal when not in excess. In short, I think to each their own.
As far as I have heard it is safe idk how much tho.
