You might be late because you just started about a couple months ago or a year ago. Even if you are usually regular like me it can happen. Also if you have a mom that might be why because ya´lls periods are lining up.

Not knowing more about you or your period it is difficult to say what could be causing your late period. Activity level and stress can certainly contribute. Age can also be a big factor. Robyn Srigley, a holistic health coach has shared a wonderful article detailing the common issues causing irregularity in ladies of all ages. We encourage you to check it out at http://www.bepreparedperiod.com/blog/why-is-my-period-irregular/.

Hope this helps! If not, please feel free to edit your question description to include more details about you (age, how long you've been menstruating, etc) as well as your period experiences.

Best wishes!
