I was on Cerazette a few years ago...and seriously nearly stabbed someone
which then in turn made me burst into tears for about 3 days... It was incredibly mental.
I've pretty much tried every kind of Pill going and they do not agree with me. I think the last one I took was microgynon 30 or something and it produced headaches. Next one (can't remember, I'll look them up) caused migraines so stopped taking them altogether.
Don't put up with evil side-effects of a Pill - there are some new ones out that are supposed to be really good, but I've never got on with them. I know why, of course, as of only a year ago but that was pretty "helpful" after over 14 years of chopping and changing and trying to find something that worked. Depoprovera was "interesting"
I really hope you find something soon. 14 days' bleeding isn't right!
