Baby’s weight...

Gen

I’m due March 26th and currently seeing my OB bi-weekly. However she’s only measuring my belly, checking my urine for protein (I think, I gotta pee in a cup every visit) & asking me about baby movements and concerns. Last time I had an ultrasound was at 18-19 weeks and she said it was a girl and everything looked perfectly fine. How do you guys get baby’s weight often? She hasn’t mentioned her weight since the last ultrasound, is this normal? It’s been 9 years since my first so I really don’t remember
