Patient : I have an event coming up and I know that if I start a new pack after my 21 day pack finishes I can delay my period. I'm on Tri Cyclen Lo and it has different hormone levels for every of the 3 weeks and I don't know if I should take the white, light blue, or the dark blue pills once I start the second pack for a one week delay.
