Hold on was your doctor saying not having a period would cause cancer because if so that is a misconception. I would talk to another gyno if you can just to get a second opinion since I am not a doctor but my gyno and the research I did said it is perfectly safe for you to not have a period. You do need to know why you are not having a period though whether that be menopause, pcos, or birth control to make sure there is no other issue that can cause cancer. Sorry I don't know much about the med you are asking about i saw say it usally takes two weeks to start working and if its not working take a 14 day break then try again but again I do not take this medication and am not a doctor so do research and talk to a doctor. Hopefully someone will be able to help. Goodluck

I personally don't get it often and I've only been told the risk of it being even harder to have children one day so if that's a concern I would get your eggs checked and if possible if they are good frozen so the missed periods won't mess up your chances of getting pregnant but personally I plan to adopt so I don't know the affordability or possiblity of stuff like that very well
