I'm 12 weeks currently and so far I have lost around 15 pounds from before I was pregnant. The only couple of things I can even imagine that are causing this is that I was on medications before I was pregnant (zoloft) and am now off of it and my lack of appetite. I just can't see losing that much weight so early on; although I guess what I've read says if you lose weight, you'll lose during the first trimester. My midwife's nurse I called said to just try to keep protein in my system and it should be fine but that's hard to believe.
Re: Losing 15-20 lbs in latter first trimester
I also lost 15 pds the first trimester. I havnen't gained anything back yet either. It's funny your talking about Zoloft. I was on Lexapro and weaned off. I had been on it for almost 5 years. Now it makes me wonder. My doctor put me on Zofran for the nausea, but it does nothing for me! Good luck and I hope things get better for you!!
