I am 20weeks pg with no. 3 and up until the last 2 weeks I was doing really well. Not eating too much, having a biscuit but not the whole pack. So why di I now need to eat so much, and rubbish too. I'm not bingeing, I am just eating too much and the wrong stuff. Anyone got a good way to eat sensibly when pg? Can some one tell me it's bad for the baby? that might stop me!
