Hi I Started Taking Microgynon 30 A Couple Of Days

Hi I started taking Microgynon 30 a couple of days before my period was due, I have now passed my due date and I have had no bleeding but do have an ache in tummy which is fine. Im due to go away in a days time and dont want a period should I double up on Microgynin or ask for Noritheterone as well
