Is there a way to find out babys estimated weight?

My last sono was at 32 weeks (I’m now 37 weeks) and they said she was weighing 5 lbs, measuring 6 days early, which made me nervous because they gain a lot more towards the end and she was already 5 lbs lol

At my doctor they make you to go to a whole different office at another location to get a sono done. But my actual Ob doctor hasn’t said anything about her weight or estimated weight at any of my weekly visits. I’m kinda curious to see how much they estimate she’s weighing now. Is there a way to find out or should they be telling me?

And every time he measures my stomach he says she’s measuring on time but the doctor that did my sono said she’s measuring early? So idk

Right now all they do at my appointments is basically just check babies heart beat and my blood pressure and send me home.
