Measuring behind?

Alexis • Baby Girl 08/22/2018 💕💕

So I had a ultrasound today to just check and make sure everything is going good with Baby Girl and everything looked good except for the fact that she was measuring at 30 weeks and 6 days instead of 32 weeks and 2 days... at my 20 week anatomy scan everything was fine she was measuring perfect and now she’s 10 days behind ?! Should I be worried at all that shes measuring small? The technician said she’s weighing in at about 3lbs but I know that can be off by like 2lbs I don’t see the dr until next Wednesday! And just a little worried 😕
