I am thirteen and a half weeks pregnant and I have had no alcohol for 9 and a half weeks (since I found out). However yesterday I had two small glasses (125ml) of white wine. I had read that 1-2 units occasionally was ok and I genuinely thought a small glass was a unit. Later I found out it is 1.5 units. I don't intend to drink ever again for the rest of my pregnancy - it is just not worth it, but I'm worried I might have harmed my baby and feel very guilty.
