how late?? stress can dely your cycle.

In your teen years, keep in mind that your cycles are going to be wacky for all sorts of reasons. Stress is a major cause. If you are a very active and sports-minded person, then that too will cause a delay in your cycles.
When I was in high school and participated on track, sometimes my cycle would delay for 2 months, but I didn't stress on it.
So take a deep breath and relax...

Stress can delay your period. Poor eating can delay your period. Over exercise can delay a period. Low body fat can delay your period.

So glad that you have not has s*x yet. It is your greatest gift. Keep it for the person you plan to stay with forever. Don't give it away to just anyone.

nevermind I got it
