I'm in arrears!!?

Ok I'm13 and I'm late for my spell. Not that late but delayed No I've never had sex so im not pregnat so Why?I'm in arrears!!?
it could be stress related or anything. If you are that concerned consequently you should see a doctor
It's okay! I am 13 and I got my interval in November but I skipped it within January and Febuary, then I get it again in March. Its because when you hold your period for the first 2 or 3 years it will be irregular (not come when expected) because our body have to get used to it. Good luck!
I be 13 got it within June and it didn't come back until September. You're fine
