2nd growth scan in 3rd Trimester

Alicia
So I had a growth scan at 33 weeks to check on my little guy. He was fine and measuring about 5lbs. I saw my midwife today at 37 weeks 4 days and they ordered another one. I'm just worried since they want to do another one. Any other moms out there that went through this? I'm hoping he's just a big baby and nothing is wrong.
