Thank you for the replies. Happy Holidays to everyone.

I heard some ladies said that it can be thyroid issue, to poor circulation, to being tall and anemic; can caused cold hands and feet in winter time..
BUT I'm a 4'11" short height and chubby girl, I'm like chubby everywhere. I'm sure 4'11" is Not tall, and I'm NOT anemic.

Yes, I had my iron levels check. I have an OB/GYN and a M.D. doctor.
All my health check-up is normal. My blood test result everything is within normal range, my blood cell count is in normal range too.

My hands and feet doesn't turn purple or white, at.all. It just get really cold, like freezing cold.. And this only happen in winter/cold weather. Never happen in spring/summer or warm weather.

Wear socks does help a bit. We tried turn on the heater--and it helps alot.
BUT last time when the heater stays on, after a while I get bleeding nose, I dunno why. It is because at night outside it 30ºF cold, and inside it hot with the heater on so my nose bleeds?
For the past four nights my husband didn't turn on the heater, perhaps he doesn't want to see my nose bleeds? He keeps rubs my hands and rubs my feet to helps keep it stay warm.

It wasn't this cold at night last week or so, it just starting to get cold. And it been raining for the past two days, so it gets colder than usual.
