I had the Mirena for 7 months, and had it removed. I got my cycle back 2 days later, and it lasted 3 days same as always. Surprisingly though, I just started my period again after 21 days! I used to have a 28 day cycle regularly. I'm 28, so I don't think it's time for it to shorten naturally just yet. I used to ovulate on day 17, and had a 9 day LP, so I'm curious to see what happens this month. We aren't TTC until the summer, but I am curious what's going on. ETA: I am still breastfeeding as well.
How long did it take for your cycles to normalize, or are they permanently shorter or longer?
