Menapause or Pregnacy ?

There is a small chance that it is pregnancy, as there always is, but you are getting close to the average age that most women officially enter menopause - the age of 50. And for you to be declared as menopausal, you need to be without a period for one complete year. But this doesn't happen all of the sudden - your periods become less and less regular over time before they finally stop. And not to mention that you have been sterilized, so the chances for pregnancy are even smaller because of that.
