OPK Confusion

Rebecca

Hello,

I've been doing OPKs for the first time & still a bit confused.

Could the OPKs with the cross beside them be my positive. One was at 8pm on Tuesday night & other was 10am Wednesday morning. When wet they only looked maybe 70% as dark as the control line. Photo when wet in comments. However, the test line appears to be quickly fading away now.

My cycle normally goes between 30 & 35 days and that was CD18 & 19.

Thanks :)
