Itchy Feet!

Kenzie
Hey ladies! So I'm 37 weeks, my next appointment is on Tuesday and I'll be asking my doctor, but I wanted to see if anyone else has experienced this! 
All of a sudden my hands and feet have become extremely itchy, especially at night! I wake up (when I do sleep lol) and scratch and scratch and scratch! It's the weirdest thing!
Should I be alarmed? Could this be something bad lol? I don't even know!
