Would a 9lb loss in 2 weeks due to morning sickness worry you? I've got a high bmi anyway so have cleared it with the midwife that I can lose weight at a sensible rate by eating a healthy balanced diet. However I've dropped 2lbs in 2 days because I just can't stand to eat much. I know baby will take what they need first so its me that's likely to suffer just not sure if I should be mentioning it at my next appt.
