andrea;

stress can do alot of thing to the body,and for women its a change in there menstrual cycle.
your period should be regular at this time. when was the last time you seen your doctor.?

i gather your having sex? i hope you are using birth-control. now your under even move stress,due to the fact your worried about this.

i get its going to be a waiting game at this point.
