Hi!
Stress has probably altered your hormone balance, and caused you to miss a cycle or two.
If you don't ovulate on any given cycle, the period won't be normal for that cycle.
If you were my patient, I would just ask you to call in, not come in, and I would prescribe progesterone to be sure the lining of the uterus is "clean" and then watch and see what happens in subsequent cycles.
Hope this helps!

also, now i am bleeding what seems to be normal...
