Help! 🤷🏼‍♀️EVAP on internet cheapies?

Hey y’all. Has anyone gotten bad evap/dye run lines on internet cheapies? I’m on cycle day 10, and accidentally reached for an HCG strip this morning instead of an opk, and got a faint line on it. Took another, same thing. I’m 99.99999% positive I’m not pregnant. I had a full, 4 day long heavy period from August 3-7 and even if that WAS implantation bleeding (which I highly doubt), I’d be 20+ days DPO at this point and would have a way darker positive on hpt. Thoughts??
