because I started my period the third week, not the fourth week w/ the placebo pills. I had previously been having my periods every three weeks, the Alesse did not seem to be strong enough. Should I start the Ortho Tri-Cyclen next week (when I should have been having my period) or go ahead and take the placebo pills from the Alesse packet, then start the Ortho? I really do not want a period 2 weeks in a row, which is what I am afraid of if I take the Alesse placebos.
