No appetite/crappy weight gain?

Hey guys, I am curious if anyone else has gone through what I’m going through. Back story here I gained 35 pounds with my son and was ALWAYS hungry even at the beginning.

Fast forward now nearly 4 years later, I’m 21+3 with our rainbow baby girl. I have ZERO appetite. Nada, zilch, zip. I have to literally force myself to eat. I’ve only gained ONE pound with this pregnancy, with my son I was up 15 at least at this point.

Baby girl is also measuring on the small side, which has me feeling SUPER guilty because I’m sure a lot of that could be prevented if I ate better/more.

Has anyone else had absolutely no appetite when pregnant and not gained much if any weight? Is there anything I can do to help get my appetite back?

Thanks in advance ladies, I really wanna put some weight on this girl so she’s not super super tiny when she’s born.
