period and birth control

Hi!! So this is my first month of birth control.  I started it on the Monday after my period, the 12th of June. my doctor told me to double up and take Sunday and mondays pill. So my question Is, since it's my first month, will I still get my period when I'm on the placebo pills? Or will something weird happen and I won't get it? What was your experience with your first period on birth control? My boyfriend and I waited a little over a week to have sex while I was on them (the instructed time by the brand of pills) and even then, we used condoms the whole time so I'm not worried about being pregnant but it would still freak me out if I didn't get my period! Thank you!
