I am currently using Levora and I am meant to switch to Ortho Tri-Cyclen tomorrow, Sunday. I am currently on my period and it is supposed to go away either Sunday or Monday, but the instructions say to start taking the pill the first day that your period starts, which worries me. Also, this new brand of birth control, Ortho Tri-Cyclen has different colored pills, white, light blue, darker blue, and green. The instructions say to start on the white pill the day of my first period. It gives me two different options to start by: Sunday start, and day 1 start. I've been trying to figure out the best way to do this but I need major help!
