Joint Pain in Hand

I'm 28 days and 2 days ~ I woke up this morning to my hand feeling like I have severe arthritis. It had been more subtle before, but is pretty bad at the moment. I looked it up and read it could be a normal reacting to water retention, loose joints, and increased blood supply. It also said it could be a sign of preeclampsia. I was just at the doctors on Monday and my blood pressure was good. So I'm not concerned really, but has anyone else experienced this?
