late period

i’m due for my period today and i’m really worried that i’m pregnant! i have the implant/rod and i have been having unprotected sex for about a month now! i know the implant/rod is 99% affective, but i’m still really worried! my period is never late and it usually shows up in the morning!

(i’ve had the implant/rod since september this year, i waited 2 months before i decided to have unprotected sex with my partner)
