My gf was on ortho tri-cyclen lo but anyways.. she went to japan for a month to study abroad and her cycle got messed up and was confused due to the time difference. .so she decided to just stop anyways since she wouldn't be having sex in Japan. but anyways.. she's back now and wants to start taking it again.. if we remember correctly she starts the Sunday after her period right? Last Sunday/Monday her period started.. today (Friday).. her period is over.. so does that mean Sunday she starts the new back? thanks!
