I did take this kind of pill a couple of years ago. I found that while I used it, I was constantly feeling "off", and had thrush almost constantly. I didnt have any random bleeding though. When I stopped using it, the thrush stopped and so did the off feeling.
I thought they were also not quite as reliable as the triphasal or combined ones?

Oops my dumb brain. I got confused and was thinking mini pill there...
What I mean is, whenevr I was on the pill it was always a mono one, I never tried the biphasal one because the mono one worked just perfectly for me.
