Totally normal :) I got my period at 12 and had pretty irregular periods until I was about 15!
It's perfectly normal to have irregular periods at your age. And hey you're all 13 like me. If you notice really unusual changes maybe go to see a doctor. But for now everything looks fine.
I'm 13 too and i've had my period like 2years and somethimes theres like 50 days between my period
Hey! Im also 13 and I started my period about a year ago. For the first 2 years or so of your period and all through out your life, its normal to have irregular and its nomal for girls out aged to have late periods! It should settle down and fall into a proper cycle at some point but for now its nothing to worry about! xoxo
