I am 16weeks pregnant and I usually have I cup of coffee in the morning and 1 cup of tea in the evening, I do have the odd can/bottle of coke once or twice a week too. Just lately all I crave is coke, I feel it really gives me a boost I need. From what I have told you, does it seem ok what my intake is so far? Can I increase to more caffeine or not as I am not aware of exact quantitys ? Xx
