At first i thought it was because i have had nausea until 25ish weeks and bad heartburn. But lately i have been so hungry and eating heaps and still i am losing weight. I have mentioned it heaps to GP and midwife and both are not concerned. So i know is houldnt be but its hard not to you know? I am overweight but have never been a big eater. I was overweight with DS too but gained 10kgs (and lost it all the day after birht). And i do weigh less than i did with him but i still find it rather odd to be losing so much.
