nope. di ko masyado maalala pero dapat nagstart ka either first day ng mens mo or last day para maging reliable yung pill mo. i was on pills kasi dati for years pero ibang brand. pero ang ginagawa ko dati is kapag di ako nakainom for some time tapos nakipag sex ako, i take 4 pills in one go tapos another 4 pills after 12 hours. pero dapat mainom mo yung first 4 within 24 hours after sex. nabasa ko lang sa internet yun dati. im not sure kung effective sa lahat, but it never failed me nung ginagawa ko yun.
no na po
