feeling full very fast !!!

Bri • Blessed❤
So lately anything I eat small or big I can't take more then a few bites without feeling super stuffed .
I can be completely starving and as soon as I take Jose first few bites it's like the hunger is allll gone n I feel super full . It's just really weird to me because in the beginning I couldn't stop eating and now I can barely finish the plate . 
BTW I'm 12w 5d 
Is anyone else going through this
