I'm 16, 17 July 6th so not far away anyway I feel guilty and scared I've quit smoking but I keep drinking fizzy drinks my diet isn't so bad but still bad I'm constant eating anything 🙄 and I can't take the folic acid after over dosing in the past I can't swallow tablets without being sick? I'm so worried I've harmed my baby and I'll make it have a disability I don't want  that and I'll still keep it and love it I'm 11 weeks my third scan is soon I'm worried there won't be anything there How can I stop worrying
