... start my period this week but so far i haven't. however, my last period started on the 14 th of last month which was a friday and i started my pill pak that sunday while i was still on my period. so if you count 28 days, which is usually my period schedule, then i shouldn't start until the 11th of this month, friday. then i will start a new pill pak on sunday. just seems a little off and i am worried that i did not start them right. i am a sunday starter but i just thought i was suppose to start pretty quick after i started the green pill week. ??
