Mirena Removal

I had my Mirena removed about 3 weeks ago after having it in place for 3 years. AF came to visit on 6/2/17 for the first time in 3 years and is still sticking around (total of 9 days now). This is my first "natural" period not influenced by birth control in 10+ years. My last "natural" period was when I was in high school. I remember heavy flows and lots of cramps. This time, it's been very light with minimal symptoms. Anyone have a similar experience or any insight for me as to when I can expect the bleeding to stop?  Thanks!
