switching pills

[llama4u448.livejournal.com]

so after having issues with BC and blood pressure the doctor at planned parenthood said my blood pressure was low enough to let me try a 3 month trial of cyclessa. I'm currently taking micronor and I plan on starting my new pill this sunday but I don't know if I should use a back up method at all or if should wait a week or a month. I can't exactly start if after I get my period or on my period b/c I spot so much on micronor that I don't even know if its a period.Any suggestions?
