I'm nearly 32 weeks and in the last 4 days I've put on 9lbs! I've not been going mad for food as I had a tummy bug earlier last week and appetite was off for a few days. I don't have any swelling anywhere and don't look any fatter. I'm a bit anxious anyway having had a previous pre-term birth (33+2) but given that the weight gain seems so huge do you think I should get checked out?
