if i take my contraceptive pill as soon as i get my period, will this mean that i get a shorter period? ( i.e. for 2 days?) i usually have a period for about 4 or 5 days but am going away soon so don't want to be on my period on holiday (holiday is 4 weeks). i would take 2 packs of pills back to back but i have done this once before and i got a lot of spotting towards the end of the second packet (which kind of defeats the object of not having a period!) please help, need replays soon! thanks
