Joint pain-wrists and fingers

Elizabeth
FTM here. 35 weeks, 4 days. The past week or so I've had really severe joint pain in my wrists and hands. It's gotten so bad that I can't grip anything and I can barely write my shower thank you notes. I know there is such a thing as 'pregnancy carpel tunnel' but this seems pretty severe and sudden. 
Any one else experiencing this? Anyone seen a doctor about it? 
TIA!
