Alah, at 11 weeks it's actually quite normal your morning sickness is settling down, a lot of us felt relief around this time! The quick fullness + quick hunger cycle is your body adjusting to the pregnancy hormones and your growing baby needs, so don't worry la. Breast tenderness usually eases off after the first trimester too, so that's a good sign things are progressing nicely. About the weight loss though, since you're not managing to eat much, better check in with your doctor just to make sure baby's getting enough nutrients, they might suggest smaller, more frequent meals or snacks that sit better with you.
