Kcanario is correct, a lot of Ob's/ midwives now (especially in the UK) say that after the first trimester a glass of wine every now and then is perfectly okay. With that being said its best to follow the advice your Dr gives you.
In my opinion and my doc (some ppl dont agree) yes it is perfectly fine. Its actually good for u. But they told me 4oz max in a glass. Im 37 wks healthy baby boy and ive had about 5 glasses throughout my pregnancy
I would *definitely* take that up with your ob or midwife before doing anything.
My sister in law told me the same thing! But I haven't had any lol
