Skipping is best done on a mono phasic pill!!
That is why you are having problems, because you are trying to skip on a tri phasic pill!
That bleeding is normal, it will not harm you.
When women use seasonale, they are told to expect almost everyday spotting and bleeding for the first few months, due to the body needing to adjust.
You do not need to keep taking your pills until the next cycle, you can stop and allow a 'period'. Usually in women with prolonged bleeding, this helps them 'bleed it out'.
You would need a new pack though for when your period is over.
