What would you do?

Carissa🐧 β€’ πŸ‘¨β€πŸ‘©β€πŸ‘§β€πŸ‘¦ πŸ’™πŸ’— Married with a little boy and coming soon a girl!
So I went to the doctors today since it's been 4 days of my back hurting. She says 2 more days off then not lifting or pushing 20 + pounds. My manger says that she's not sure if I can return due to the limited things I'll be able to do. Which I can do plenty!!!!!!!!! I'm so mad and have no clue what to do. I feel guilty for being pregnant.
