Why no period?

Jada • Life's too short and so am I

I’m on birth control and have never missed a pill and have never taken it later than an hour and this past four weeks every day has been on time. I’ve had sex with my boyfriend where he finished in me three times over the last four weeks but I’m not too worried because of how consistent I am with taking my pill. I’m on the second day of placebo pills and still no period; I don’t have any discharge either. I’m just getting impatient lol. Any comments?
