Gemma, I ate heaps more in pregnancy and only put on 11 kilos in total, 4 of that fluid. (which I lost in four days with blood pressure tablets!)

For me breakfast was a 600ml Big M (chocolate or coffee) and two croissants, I'd have a chocolate bar for mid morning snack, (and sometimes a bowl of Coco Pops); then lunch was stirfry with noodles, or soup with bread (big helping) or chicken and chips. Afternoon tea was a bag of chips and/or a chocolate bar. Dinner was whatever I bothered to cook.

So I ate heaps more than you and didn't put on a lot of weight.

I think your diet is fine and you shouldn't be putting on too much. Mostly I exercised a lot, (swimming and walking) so that might have been the reason I didn't put on a lot of weight.

Best wishes.
