No appetite?

hey guys i’m 15 weeks and for the past few weeks i’ve been struggling to finish any of my food which has caused me to lose around 10lbs. Whenever i eat i take a few bites and i’m stuffed. i don’t know if this is normal or not. It seems like it’s more common with women who were experiencing morning sickness but i didn’t. I started my pregnancy at 126lbs now i’m around 115. I’ve tried eating small portions throughout the day but it’s just keeping me at 115. Has anyone experienced this if so how’d you get those extra baby gains? Sorry if this doesn’t make sense i’m not the best at explaining things lol
