period

Re
So my period has been weird lately I had my period twice last month even when my pack of pills wasn't gone. So this month I started a new one and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> is saying I'm 5 days late from last one. What does this mean? Should I go to doctors or wait till my pack finished and see if I get it ???
