I would also recommend a pregnancy test--I ALWAYS do.
If you
missed a
pill it can be enough to cause a
period that lasts forever. Often by the time you get to the placebos, you will have stopped and won't have your regular period. Usually it is best to continue with the pills daily and when you start your new pack things will usually sort themselves out. If this continues to happen frequently, you may need to change your pill for awhile.
Good luck!
