Knuckle pain

The last few weeks before bed my knuckles have started to hurt, I assume its from swelling? But when I wake up in the morning bending my fingers or trying to make a fist hurts a lot. Almost feels like I cant actually do it, it hurts that much wometomes. I'm a first time mom so body changes and everything going with pregnancy is new too me.

Has this happened with anyone else? Is it normal?
