Hi
Welcome to the health care magic , thanks for query about such nice question.
Let  me explain in detail about  certain myth about  
OVARIAN CYST.
Cysts are often caused by hormone changes.
Using BIRTH CONTROL PILLS ( famynor) can sometimes help regulate hormone levels so that cysts are taken care of.
Your gynae will likely want you to come back afyer you have been on the famynor to see if the cyst is gone.
At that time the doctor may suggest  you stop using the medication or , if indicated , you may need to continue it  for a bit longer..
Once you stop famynor , as long the re are no medical concerns, you should not have problems in future .
Many women use birth control pills for purposes other then preventing 
pregnancy .Then they stop taking them when they want to conceive.
Famynor is a 
contraceptive and also help  regular your menstrual cycle , if the irregularity are occurring due to 
hormone imbalance.
Hope this information will help you .
Further any question I will reply happily.
Good luck.
