Just started happening today...

So today my wrist, hand and fingers started feeling weird. Like they felt weak, then it felt like tightness. Then it was like when I tried to straighten my fingers out they didn’t want to move. Then they were fine. A few minutes later it happened again. It has done it several times in the past hour. Anyone else have this? I don’t know if it’s pregnancy related or not. Just confused cause it’s never happened before.
