I was out for dinner and drinks with friends this evening and was on the soft drinks. However, I’ve just been counting up my drinks and realised I’ve had four cans of Diet Coke over the course of the evening. I know it’s not a good idea to have too much due to the caffeine, and am now really worried that I could have harmed the baby. I’m 21 weeks pregnant. I honestly don’t know what I was thinking!
