VFL after period?

So, I just finished my period and had a wondfo strip from last unsuccessful cycle so thought eh why not take that with my ovulation strip!? The wondfo strip came back with this line. I then took a FRER. Is this just a bad test? I’ve read about people getting pregnant before a period, having a period, the. Getting the positive sometime after. I don’t think I’d be one of those people but now I’m confused.
