I want to skip a period... I am going to start tricycle lo... I have heard 3 suggestions... (1) is to take the first 3 weeks then to start a new set right away, starting with week 1...(I heard this could be a problem because of the varrying harmone levels in this medication.... other thought is that tricyclen has different levels of hormones from week to week and it is better to do week 1 (for 2 weeks using 2 packs) then week 2 for 2 weeks then week 3 for 3 weeks? the third suggestion is to do week 1,2,3 then 3,2,1... What is the best way to avoid a period while vacationing?
