Areola changes size??

Does anyone else’s areolae change sizes?? They look pretty normal sized most of the time but sometimes they shrink and look like almonds. And sometimes they expand a LOT and look twice as big as they normally would. It doesnt even happen, like, over my period or anything it just happens randomly throughout the day. Im not always checking them tho lol but like i’ll see them one sized before changing clothes and then five mins later boom different size. Im not pregnant so im not really worried about anything, just curious if this is a common thing.
