On the calendar here in Glow, it says my cycle repeats every 22 days (Which isn’t it every 28-30 days?) and I haven’t gotten my period yet. I was suppose it have it yesterday. It is probably mostly because I am still young and my cycles may prove to be irregular. I also have never done anything sexual, not even a kiss so there is absolutely no way I could be pregnant. (I am almost 13.. and this upcoming period will be my second. I am worried if it will come or not.)

My Mom and my sister never really had extremely irregular periods. The most irregular period my mom has ever had was 13 days after the expected date. I need advice!
