I put on 6 kg in first trimester, not because of what i was eating, it was due to lack of doing - i had severe fatigue and basically lay on the couch for 2 months! Since then i have had a steady weight gain of 1.5kgs each month which my dr is happy with. i don't worry about the weight anymore - i was absolutely stressing about it initially. Can't do anything about it other than trying to eat well and keep moving. Will deal with it after baby is born.
