Has this happened to anyone??

Hello! I am 6+wks prego. I need advice. I am freezing. My hands and feet are cold, but my legs, butt and abdomen, sometimes face is hot to the touch! I am burning up. My oral temp is normal.  I am so uncomfortable. I have to put ice packs on me while trying to warm up under a blanket! This has been happening for over a week. I called my OB/GYN and they said they have never heard of this and to call my PCP. I called my PCP but I'm waiting to hear back from him. Can anybody help?
