Really short periods. Normal??

Hi! I recently got my mirena taken out mid December. While I had it, about six years, I did not get my period. Since I’ve gotten my mirena removed I have had really short periods. In January my cycle was 2 days, and so far in February my cycle has been 2 days and I don’t think it’s going to go to a third. Has this happened to anyone? Before I got my mirena my period would last 5 to 7 days. Just curious if anyone else has ever gone through this. Thanks!
