Premom hcg - false positives?

I've never used these tests before and just wondered if anyone has? After looking at amazon reviews there have been some people with false positives and just wondered if anyone has had the same as me on here?

Spotted for 2 days 11dpo & 12dpo nothing today 13dpo. AF due Saturday, so just thought early AF arrival.

Tested yesterday (top tests) premom looks positive, Wondlo negative

Premom test today (2nd pic - 1st test yesterday, 2nd test today)

Not convinced with this one, but I'm holding out some hope 😅 will order frer and test again, just wanted to see if anyone has had experience with premom hcgs.
