Yes, I am experiencing the same thing. I think it has to do with hormones and anemia!!
I go between freezing and omg I'm so hot I must strip. I'm 7wks trying to sleep at night I'd fuuuuun.
I was like that for both my other pregnancies and this pregnancy too. It lasted the who time.. I was always cold. I mean long sleeve shirt in 70 degree weather.. it's a hormone thing and it is fine.
Your body is just focusing on sending blood to where it is most important... Your uterus. I've been experiencing the same symptoms and I'm 6 weeks with my third. I didn't have this symptom with my other two babies. It's crazy how every pregnancy is so different.
I have been doing the same thing!!
