Ovulation test help

Kelley

So this is day 3 of my fertile week and 1 have been taking the opk and yesterday the second line wasn’t super dark but almost there but today it is way lighter then yesterday. Anyone experience this?

I can’t believe it is that short and I missed my peak, I’d be so sad. Really hoping that December is our month after mc in July 😩

Is clear blue opk worth the money to not have to deal with these dumb lines?
