My period is late

Ok so on <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> it says my period is 8 days late which i whatever, my period has been a bit wonky lately because of stress and other stuff but normally it isnt this bad? I'm on the pill and I'm already halfway through my placebo week and nothing? I'm sexually active and normally i make him wear a condom but one time i didn't. He pulled out but i know theres still a chance and tbh I'm kinda freaking out internally?? What if I'm pregnant?? Can i even get an abortion without my parents knowing? My dad would kick me out. I don't know what to do please help
