I'm 33 weeks and I feel the same, I'd eat and feel a little sick afterwards.. I'm not eating as much as before. I read that the baby is taking up more room now so it's normal..
I jesz got over a stomach virusz...it wasz filled with painful random stomach achesz and plenty of nausea and runny stool(tmi)...and it seemed like everytime I would eat tha pain would come back so it didnt leave much an appetite...hope you get better soon...
I would get full and queasy once I was further along witg my first. Maybe baby is taking up a lot of room? Do you have anything else like diharia?
