not feeling pregnant

Nicole
I am 19 weeks and two days but I don't feel like I'm pregnant 😭 it's weird to say but about a week ago I heard my baby's heartbeat and everything was fine. In a week I have my anatomy ultrasound and get to find out the gender (SO NERVOUS) hoping everything is okay. But I just feel like I haven't gained enough weight and my stomach doesn't look like a pregnancy bump. I know every woman is different. I'm just like freaking out a little inside lol
