Mirena & Periods

So I had my mirena IUD in for 2 years, and got it out due to symptoms that it was causing and my mental health.

Hubby and I want another baby, but we were hoping to wait a few months from now. We have been having safe sex, but I am now 3 days late for my “next” period. I have only had one period since i’ve gotten my mirena out about 2 months ago.

Is it normal to be late, or inconsistent/irregular after the removal?

Thanks for any of your own personal experiences!
