Salvia Ovulation Test Help!

Sick of peeing on sticks so I bought the ‘maybe baby’ saliva test. I got it in the mail on the same day I started spotting for my period. I tested, not realizing you need to fast before and saw some ferns (fertile)..So I tested this morning first thing and FULL furning. On Day two of my period?! What in the heck? Anyone know, is this possible from period hormone changes? Could I actually be ovulating and that’s why I haven’t got pregnant for the last nine months?! Maybe I’ve been missing it this whole time? 🤷🏽‍♀️

FYI: The area on the side where ferns exist is the only area with saliva.
