Ladies, any of you experienced a cycle as short as 19 days?

I'm 33. My periods have always been very regular. I was expecting my period to come on the 27th but for some reason I started bleeding today more than one week earlier than expected. My cycles are usually 25 days but this time is only 19 days. I don't recall anything like this happening before. I don't feel anything abnormal apart from the typical bloating and light cramping. I have a copper IUD if that makes any difference.
