I started getting bleeding every 15 days for about 5-8 days. So my doctor prescribed Mononessa 28s. I started on the correct Sunday after/during a period as she instructed (days 1-3 I still had my period -sun-tues-). I am finished with my first pack. I began bleeding on day 15 of being on the pill (just 12 days after starting the pill). It is extremely tiring having period every two weeks and I was surprised my period arrived in about its time period of 10-15 days after the last.

I am on the birth control to regulate and hopefully only bleed once a month. How long does it take to get "normal?"
