I used cerazette for over a year. It totally stopped my period for the word go. I came off it for a little break to get a few monthly periods cos I didn't feel right not having one iykwim.
I fell pregnant when I took that little break.
its hard to tell if it will stop them altogether, it'll be constant worry every month, and I know how you feel.
Hope it helps
Thanks very much for the reply...I don't even feel like its coming on, I'm in great form actually where at this time of month id be either full of tears or fit to kill someone lol brilliant stuff if its keeping my periods away but like u said its a worry not having them...I can see myself spending a fortune on tests every month!!
