Ring is stuck

No seriously my ring is stuck. I don't want to bug my Doctor with this silly question so I came on here. 
It can twist around my finger with no problem but as soon as I try to pull it off my finger turns purple. I've try soap and creams to try to get it off but nothing. I only have 7 more weeks till my due date so I'm woundering should I just not worry and hope my fingers don't get bigger or swollen or should I keep trying to remove it? Any trick you guys might have for me? 
By the way when I do get swollen it doesn't cut off circulation but it just doesn't feel comfortable
