Pos OPK - NEG/HELLLLLLAAAAA FAINT TO THE POINT OF GUESSING HCG

Is it true opk’s pick up before an HCG?! Because well, I will be 13dpo tomorrow morning, I started getting hella positive OPKS, and lines on tests only I can see. Literally no one else can - I might even be crazy and not actually see them. Maybe it’s all in my head. Period is due in 2 days.

Is the opk showing me I’m pregnant? Is it normal right before my period. What’s going on in my uterus because I’d love to know
