I have been on Cerazette for about a year and a half now and it's been working fine, periods stopped after the first month of taking it and there was no pain however, just recently I have experiences some bad pains/cramping, i used to get this a little when I had periods and it feels the same only worse. The pains are worse in the morning and subside a little through out the day, it only happens once a month and for a couple of days and finally there has been no bleeding, is this normal?
