17/01-11/02-13/03-12/04-09/05...I jst wanna know if I should be worried or not...becoz it's confusing me...at times it comes early and the next it comes on time.
You seem irregular and if you are young, that's very normal. You are having a cycle on a normal basis but just at different time intervals. No worries with that. Other than being annoying, it's not harmful. good luck
