Weight Loss: Concern or no?

Emma • Mum to Harlen Jane🌷July 6th,’18 & Nolan Stone 🍭June 28,’19

I’m currently at 32 Weeks today, and in the last two weeks I’ve lost 4 pounds. I had been gaining at about a pound a week since 8 weeks ago, so I was right on track and all of a sudden I’m now losing weight and starting to appear skinnier in my arms and legs. Yes it’s only 4 pounds, but I’ve been consistently gaining weight at a steady pace until now. My next appointment is in 6 days, do I wait or call tomorrow
