I've had my period for about 4 years now, and its been pretty regular (29 day cycles) but then the last time I had it was on February 16 2009 and missed about 5 periods. Then I got it on June 4 and had it for 6 days it was really light (hardly even needed a pad). I was suppose to get it on July 3 but it's now 11 days late. what could be the problem (is it maybe because I'm stressed about not getting it?)
or could my cycle just be switching?

So I still have not gotten it yet, it is now 15 days late.

Do you exercise a lot? There are many factors that can affect your cycle. I often miss 4/5 months on my heaviest training months... Diet and weight can also have a big impact!
