Having a regular day, away at relatives for Christmas. I was bathing my daughter a little while ago & noticed my fingers are deathly white & my nails totally blue! The palms of my hands are also really blue! 
They don’t feel remotely cold nor am I cold. I’ve been in a warm, toasty house all day. I wouldn’t have noticed if I hadn’t been specifically looking at them.. but I am now sat with them on a hot water bottle to see if it helps! I do have pins & needles starting .. so I assume my circulation is returning!
Anything to be concerned about do you think? My feet look normal thankfully! If they don’t go back to a normal colour, should I query with a medical person?
I’m 27+5 ..
Thank you!
