After 7 months of use of Tri-Cyclen Lo, it still gives me breakthrough bleeding so my doctor prescribed me a new pill that may control my cycle better, Linessa. My doctor said I should start Linessa on the day I am supposed to start my next pack of pills, which is next Monday. I am now on my placebo pills. Should I wait till next week to start it or should I start asap? Also, should I use back up protection now and on the first week of the new pill? Or am I protected right away? Hope you could help me out. Thank you.
