A few days after my period ends I just blissfully forget about it until one day I wake up and notice my crotch looks like someone was murdered there. Super duper fun.
I don't think so. Basically you are tricking your body into thinking you are pregnant and leaving it that way. Less eggs are released, less uterine walls being replaced. That should mean both more eggs later in life and less risk of uterine cancer.
Of course you should ask a doctor about it. They gotta prescribe it anyways.
