no appetite 🤦🏼‍♀️

I just hit my second trimester today, I’m having twins. I don’t know why but this entire pregnancy I have had no appetite at all, I eat one small meal a day and that’s all. after that I feel full the rest of the day. I know it’s not good for the babies and I really can not eat more or I feel way too full and sick. I just don’t know what to do because I’ve already lost 14 pounds and I know at my next appointment I’m gonna have lost even more. I just want my babies to be healthy and I feel like they aren’t getting enough nutrients.
