So I have started to lose weight now that I am in the third trimester. Three weeks ago, I had gained 20 pounds but now I am down to only 16 pounds above my pre-pregnancy weight. Has this happened to anyone else? I first noticed this happening a week ago so I tried to eat even more and higher calorie foods. I don't know if I should be concerned. I have a midwife appointment this coming week and I will be sure to talk to them about it. I was just curious if anyone else had a similar experience.
