So far I've gained almost 30lbs.
25 pounds of that was in the first trimester when I was still able to work. Odd since I can't seem to eat anything at all. I seriously only eat about 1000 calories a day on a GOOD day. And a lot of that gets thrown right up too. I have NO IDEA how I'm gaining so much! It doesn't seem to make sense. (Don't worry the baby is really healthy and actually measuring a bit ahead of dates; I take a number of vitamins and supplements also... and most of the time I keep them down.)
Most days I eat an apple for breakfast and then I try to eat something for dinner. Usually I just look at it and can't seem to get it down. I used to love food; now it's a chore and I can't even force myself to eat it because as soon as I do I have to go limping to the bathroom. (I have terrible SPD so I can't move very well.)
I lost 11lbs in the first trimester and I've almost gained all of that back now, so technically I still weigh the same as I did when I got my BFP but if I hadn't lost the 11lbs in the first place I'd probably be at an 11lb gain.
