Can I trust it?!

It’s been almost 7 weeks since my D&C. Initially I was getting positive OPKs, I assume due to the remaining HCG.

I’ve since been getting negative OPKs, but I’ve just taken the one below (bottom test- top is yesterday’s just for reference) and it looks like it’s getting on for being positive! My question is- can I trust it? Or has it been too long since the D&C?
