Finger swelling: pregnancy or period

Have any of you ladies ever experienced your fingers swelling in either early pregnancy or was It just your period coming along? My first pregnancy I only swelled in my toes towards the end and from what I’ve noticed as far as my period symptoms, swelling has NEVER been one of them. I can’t even get my rings off. I noticed It this morning. I’m 6-7 days until I’m supposed to start. Thanks!
