Anyone taking birthcontrol pills!

Hi Ladies,

According to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>, I’m 12 days late on my period, I have missed more then 3 pills last 2 weeks ago I remember I had sex on one of those days that I missed the pill, but I quickly remember like the 3rd and started the one I missed from the previous day and the one on that day. This will be my 4th month (4pkg) on Birthcontrol pills. And I haven’t missed any period. So my question should I be concerned!? (BTW I’m on APRI.)
