Need advice mamas

So i am 30 weeks pregnant with my second based off her growth scan but shes a chunky baby, baby dropped like three days ago, today i had an ob appointment and belly is measuring 34 weeks and she started to push on my belly to see if she can see if its more water since my daughter was more amniotic fluid than baby and she was like oh yeah mostly baby in there and scheduled me for an ultrasound in 2 weeks to be checked. I didnt see a doctor until i was 22 weeks because i was having complications with insurance so my due date has been odd and moving alot. Should i be worried my belly is measuring so much bigger??
