Baby measuring

Talia • Pregnant with baby #2!
Hello all,
I am 33 weeks FTM
I saw a post today about how big your babies are measuring and how much they weigh? My doctor hasn't measured or weighed my baby. Should I be worried? When I go in for my appointments it's usually like 5 minutes, I pee in a cup, he listens to the heartbeat and pushes on my stomach a little and that's it....
