Hi, I had a similar experience, while I was going through a divorce, my periods stopped. I was having hot flashes. The docs performed all the usual tests and determined that the cause was stress. Ever since, whenever I feel the least bit stressed, I miss periods. Sometimes its for 2 - 3 months. It has never lead to anything of concern for me and I hope the same is true for you. Take a minute and think about whats happening in your life, this could be the cause. Good luck to you.
