My girlfriend give me the guilt trip every time she sees me...I do not drink soda...I can not have caffeine but I drink carbonated beverages like flavored seltzer water and club soda etc. she claims to have reads somewhere no carbonated drinks...however like I told her, I spent my first trimester with such morning sickness and I lived 24/7 on gingerale...my little bean is healthy and could not have imagined those first 12wks with out my gingerale.
as always moderation is key, however coke and stuff have tons of sugar and caf that you really do not need.
