I stopped taking my bc pills

They were making my periods last for two weeks so I stopped taking them. On my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> app it says I should of gotten my period(today would of been the last day) 
I haven't gotten it. Should I be worried or could it just be from not taking them anymore ?
