Late/missed period??

According to my glow calendar I’m six days late but according to my Apple calendar I’m only two days late. Glow tends to be more accurate but I did take plan b over three weeks ago so I know this can delay my cycle I’m just not sure for how long. To make it worse my boyfriend and I haven’t been exactly safe recently, also not on any form of hormonal bc (smart!). My cycle is never longer than 32 days so being on day 38 has me SCARED lol. I’m probably overreacting but I’ve had zero period symptoms which I ALWAYS have the week leading to my period and have taken some sus looking pregnancy tests. I’m pretty sure this will be a missed period but what do y’all think? Is a missed period common side effect of levonorgestrel? First test is from last night and second is from this afternoon.
