Im almost 24 weeks pregnant and i have my days where i cant eat either and i wasnt gaining weight. i had to force myself to eat even if it was a couple of spoons but i started drinking ensures when i cant eat and it helps alot i did the same with my daughter as well and she was 8 pounds on the dot at 37w0d
I don't have much of an appetite either amd have also lost a lot of weight, but my Dr said that as long as baby is growing and healthy, and I take my vitamins, it doesn't bother him.
At almost 24 weeks I only have days when im really hungry... most days I have to get myself to eat.
My first child I never ate. I was sick all the time too though. This time I wasn't hungry until a few days ago and I will be 15 weeks tomorrow. I'm making up for it though now lol.
