Is amenorrhea from taking a progesterone only pill unsafe?

I am taking a progesterone with the sole purpose pill and haven't have my menstrual cycle contained by over a year. Is this at adjectives noxious?
Answers:

Which is the undamaging time for SEX?

Of course not. Otherwise doctors wouldn't prescribe the drug to be used this course. Many women experience this condition while using progesterone-only contraceptives including the Mirena IUD, the shot and the slip.

I bleed when I work out, is that everyday?

no it's typical to not own a length while taking the pill, i be on the pill injection for 2 years and never have a single spell within that time, great.
