Cycle irregularity post Mirena removal

I had my IUD removed in June and had my first period which was super light and only lasted 2-3 days in July. I then had a normal period about 28-39 days later in August from he 4th to the 7th. But now I haven’t gotten a period since that. I’ve done like a million pregnancy tests (plus a blood test) and I’m not pregnant.

Just wondering how long some of you experienced irregular cycles after getting your mirena removed? We are TTC so it’s hard with such irregular cycles.

Prior to the mirena I was on birth control for about 5-6 years and prior to that I don’t even remember what i periods were like haha so I don’t know if this is my new normal or just my body still taking time since the mirena was removed.
