It's not really that weird, at least to me.
I mean, I remember when I was younger and used to skip mine for more than 2 months, my mum was always like: it can't be like that, you need to go to the doctor. And the next day, I finally got it.
wow it was reverse with me...I used to want to go to the doctor after 3 first years of having disorganized periods, and my mom said that it happened in the first years
It's "irregular" not "disorganized"
