16 weeks 2 days no weight gain is this normal?

Kari

So I’m 16 weeks 2 days haven’t gained any pregnancy weight had 5lbs lost 2 then lost 3 gained 1...now back to my before pregnant weight.. ( and I’m not complaining about no weight gain) i just cant ever seem to eat a full meal without getting full quickly. From ultrasound i seen baby is growing and healthy and is pretty long but the dad is 6’1 -6’2 so its to be expected(and my bump is coming you can see something)My obgyn doesn’t seem to be alarmed. When does that appetite kick in?? because i feel normal still i mean i get hungry but can only eat small portions. Afraid it will hit me all at once😱
