Measuring big

I’m looking for advice, or maybe someone to just ease my anxiety. 😂 I’ve had a fairly easy pregnancy, so I’m thankful to have made it this far without concern. I’m currently 34+1, and the baby is measuring at 37 weeks! I had a growth scan at 32, and she weighed in at 4lbs 11oz. Today when I measured at 37 weeks, my midwife seemed a little surprised, and couldn’t believe how big the baby felt when she was poking around on my stomach. Has any one ever experienced this? Does measuring big mean possibly delivering early? Maybe she just had a big growth spurt, but all I can think about is her arrival!
