Post-Mirena Changes

🍈 Kaitie • Married 11/3/18 | TTC #1

Hi all. I had Mirena for 7 consecutive years (with a new one inserted at the 5 year mark). In high school, before BC, I had extremely heavy periods (having to change an overnight pad between every class and still leaking through) that would last 2 weeks, but little to no other symptoms.With the Mirena, I had 7 day periods with very light flow. Now that we're TTC and the Mirena is out, I have 4 day periods that are pretty average flow. Could this be a side effect from having Mirena for so long or could it be age-related? Just wondering if I should expect my high-school periods to return at some point.
