Why did I miss my period?

Its fine just relax that will only make your period come at the latest time possible lol for me when I get stressed I get my period 36 days after my last period and thats fine some women get their period earlier like you get it every 18 to 21 days but other get it every 28 or like me every 34 to 36 days but theres alot of things that can make your period come late so dont worry Im positive nothings wrong with you :)
