Anyone get cold during TWW? (Especially freezing cold feet!)

Does anyone else get really cold during TWW?? Especially, cold feet (and hands), but also just an overall feeling of being cold - even though the temperature in the house hasn't changed?

I started really noticing it last cycle because I was constantly shivering and could not get warm, even though my temp was higher until AF showed up.

I'm 2-3 DPO right now and it is happening again! I was comfortably warm during AF and through my fertile window... The day after O, I started to notice my feet were cold on and off - now a couple days later, it's constant again...

I started searching... some of the stuff I read hinted at the possibility of having a "cold uterus"...? Just wondering if anyone else has gotten really cold during TWW? Good sign/bad sign? Does it mean I have a "cold uterus"? Anyone else??
