Nutritionist

Hello. I saw my mfm a few days ago and they are referring me to a nutritionist. I've always weighed what I do now (5'5 and 110pds). My last pregnancy I made it to 21 weeks and didn't gain anything ( was not preventing that).

I'm not throwing up, not nauseous, etc. Just have hard time gaining.

What can I expect other than the obvious "eat more"?

I can only force so much food inside me.
