No appetite??

Christine
Hello!!
I'm 30 weeks today, and the past couple of weeks I have had to force myself to eat, and I even forget to eat a lot of the time. If my husband and I go out to lunch or dinner, I only manage to eat half of my meal at the very MOST. Now I eat about a third of my meal and I just can't eat. I had a lot of issues with morning sickness most of my pregnancy that aren't really there anymore. I'm only 4lbs or less over my pre-pregnancy starting weight, too. Luckily, my little guy is healthy and growing but it's like I can't eat, and I'm losing weight and gaining baby. 
Anyone else having similar issues?
