should i take a test?

i’ve been using the patch for 2 years, and have always gotten my period. some weeks my period will get fucked up and be late by a few days or even early. i’m 4 days late on my period but for the past two days i saw a tint of red while wiping so i was assuming it will be here within the next few days. getting kinda nervous here🥲 should i test or wait?? also don’t come at me saying BirTH COnTRoL ISnT 100% EffEcTiVe- girl i know that!!!!!
