Midwife said I should only gain 3 more lbs!

Sa

At my 28w appointment I had gained 22 lbs total. BMI normal pre-pregnancy. Midwife reminded me I’m not eating for two (thanks I know) and that she wants me to gain no more than 3 lbs. I’ve been gaining a lb a week consistently for the past several weeks. I feel so sad bc I honestly don’t see how to stop this trajectory! Been working out 3x/week with no weight changes
