16 weeks and only gained 1 pound?

Trish

Hey all, I’ll be 16 weeks tomorrow and have only gained 1 pound since my pre-pregnancy weight.

I was really sick until around week 14, and now the nausea and symptoms have gone away without any weight gain. Does this seem normal? From the sources I read online, I should be gaining about a pound a week from week 13. Is this an accurate estimate or is it less?
