I think everyone deals with it differently.
With DD I took it after the 6 week check and I just bled brown blood constantly. It never stopped. I dealt with it for six weeks and then stopped taking it. It was awful. I then went on the depo and found the same with that - but it is essentially the same drug anyway.

Considering I didn't get AF back for 10months with DS I'm pretty sure the mini pill caused it.
