Huge baby 😳

So I'm 32 weeks 4 days, and today i had an ultrasound to check my baby boy's growth, my doctor was initially worried about him being too small because his cord is attached off center on the placenta, but it's actually the opposite - he is already 5 pounds!!! Apparently that's the size of a 35 week baby. I am so happy my little guy is nice and healthy but now i'm wondering just how big he will get and if this means i will go into labor super early or have to have a c section.... Does anyone else have a big baby or have any experience with this??
