I didn't in the 2ww, but ... (pregnancy mentioned)

did start drinking a half a cup almost every day with lots of milk after I got my bfp. I have been wondering about this myself, if it's really necessary to abstain either while ttc or while pregnant.

I drank a lot of hot green tea with lots of lemon while ttc and still enjoy a cup from time to time.

I think soft drinks are worse than coffee and agree with you about the decaf stuff.
