Sorry Minnow I'm a bit slow today!!!. Yes hopefully it will return to normal soon. Microgynon is the only pill that I have had this happen with and I had only been taking it about 8 months so if you have been on it a long time it might take a bit longer to return to normal.
i know this message is old, but thought i would reply anyway!
i had super long periods (2-3wks) and then super long cycles (60days+ sometimes) after coming off microgynon last april. i am now 29wks pg though! do you take your temp? it is so difficult to know when you are fertile with periods all over the place isn't it? but i found that temping helped!
