Ladies I have had no appetite at all for about a little over a week now. Found out at the Dr's I lost 4lbs from my last drs appt 2 weeks ago. I eat, just to put that out there, but it isn't a lot. I drink to keep myself hydrated. My Dr didn't seem worried and said baby was growing as she should. Just for me to try and not to lose anymore. I don't have a clue how she expects me not to lose when I wasn't even expecting to lose the 4lbs that I did in 2 weeks. Have any of you ladies get to damn near the end and not have any kind of appetite?
