Reduced Appetite

Before I got pregnant, i could eat!! I was just hungry and was more of a snacker. During my forst trimester, my appetite dropped immediately and we blamed it on morning sickness. Now, at 20w7d, I just don't get hungry. My husband has to force me to eat. I never want anything to eat either. When i eat, nothing sounds good and i end up getting a salad so that our baby can get nutrients, bur i still never want anything to eat. We cant figure out why I never want to eat anymore either. I am overweight and i have actually lost weight since getting pregnant. (About 16 pounds. Wooohooo!!!!) However, i am worried about why i have lost my appetite. If you havr any suggestions or insight, i would appreciate it. If you know any tricks to make me get my appetite back, i would appreciate that too.
