Yeah its normal And don't worry about the baby he or she gets everything from your body its you who will feel weak so eat even though you throw up.good luck. And CHEERS....
That's exactly how I feel all the time but I get full supper full off of little amounts. Some ladies told me don't force myself to eat and buy Ensure so the baby gets all the nutrition it needs one a day it says. I had my bf buy me some today and this cayenne pepper icecream I've been craving lol. I'm 7w 2d good luck
