Weight Gain BUT Barely Showing 🙄

Idk if this is a good thing/feeling or just weird! I was 128lb before my pregnancy, I’m 19 this is my first pregnancy 👶🏽🌸 I’m 19 weeks weighing a little over 150 barely showing a baby. Idk if I’m just gaining weight because my face, boobs, arms & legs gotten bigger just not my belly. Is that normal? Its like my body fat is getting fatter only, ik I do eat a lot now! Did any of you gain more weight in your pregnancy, barely show & gotten thicker after pregnancy?
