1st Tri. 2nd baby--- feeling chilly

Dee
This is my second child and I'll be 6 weeks along Friday. With my first I remember being hot.... All the time! Esp towards the end I was running around in shorts in December lol. But this is weird for me. I stay bundled up but I either feel like I can't quite get warm or I get warm and then get cold chills.
Anyone else experienced this?
