Birth control HELP

Kirsten • I`m 18 and in love with my boyfriend of 3 years just using this app to monitor my period and learn more about my body
It's my first time on bc and I'm taking the pill (minastrin fe 24) and my doctor told me to start it the first day I got my period.  So I already had my period for this month but now I'm onto my 2nd reminder pill and she told me I should have periods during these.  So should I have 2 periods this month or is it normal to maybe skip during the first reminder pills and get it next month.  I'm so nervous because I'm very sexually active with my boyfriend.  So should I have 2 periods this month? Or is it ok to not get my period during these reminder pills?
