I had mine removed in February after having it for 11 months. The day after removal I started bleeding, it was very light and had some small clots (which reminded me of small dots) and I bled for 11 days. Then I ran these cycles:
37 days
26 days
27 days
27 days
29 days
I track my cycles on http://www.mymonthlycycles.com
Looks like I went back to normal fairly quickly. My symptoms disappeared completely by the 3rd cycle.
