With DD who's just turned two, I put on over 5 stone during pregnancy. I literally just ate and ate particularly in the first trimester and felt constantly nauseous unless I was eating some bread or carbs of some description. Having always been about a size 12 I shot up to a size 20
and after working really hard for over a year to get it all off, I swore to myself I wouldn't do that again as it really affected my confience levels, I stayed in for months after DD was born, and I'm such it also contributed to high blood pressure during my pregnancy and eventually, my induction.
Anyhoo, I'm around 7 weeks pregnant again atm, and seems I forgot just how horrible early pregnancy is. I feel rough THE WHOLE time, and can't see how I'm going to get through it without turning into a blob again. I've tried so so hard to not eat carbs but where I have a sald for lunch literally every day, the thought now makes me heave and all I want is marmite on toast
. I know it sounds like a silly worry, but I'm truely terrified I'm going to get so big again but if I don't eat carbs (loads of them, not a sensible amount) I have zero energy and am constantly gagging. Noty much fun with a toddler to look after too 
How does anyone go through pregnancy staying the same size? Tips anyone?
