Not eating

Ally • Type 1 diabetic & first time mommy! Due in August, so excited to meet my little peanut! ♥️
I'm 7w5days today and since Christmas Day I have not been wanting to eat anything at all. I try to take a bite of somethings but I just cannot make myself eat. Not that I feel sick really just I have no appetite and cannot make myself eat. I'm scared that it's not good for the baby. Yesterday all I ate was two boneless chicken wings at 8:00 pm. How can I MAKE myself eat? Also I've lost 7 lbs since my last ultrasound at 5 weeks?
