Post IUD Experience

Hello all, I recently got my Mirena IUD out. While it was in, I completely stopped having my period. About three weeks after it was out, I had a very light period and now my next period is late by a couple days (and I am slightly worried because me and my bf have only been using condoms now)

I am wondering if other people experienced this. Did your period come back right away after the IUD was removed or did it take several months before you were regular again?

Thanks!
