hey, in my experience with birth control (alesse especially), the more you fiddle with the timing, the more likely you are to have spotting. if i were you, i would just continue my cycle as regularly as possible, and wait for the spotting to stop.
i know the spotting is a real drag, but the more you change the timing of your cycle, the more spotting you will get. Once with alesse while i was trying to skip periods i was spotting on and off for 6 weeks. it was horrible.
