is a progestone analogue. Though rare, it can cause some side effects like weakness and headaches
and body pains. It is also implicated in some cases of stroke
. It is used to treat some diseases like amenrrhea which is absence of mensus. So obviously the medication did not work. What you can do is to meet a gynecologist again so that they will be able to treat you better by changing your medication or such.
I hope this helps you.
