LH test help


Hi friends!

Today is CD 21 for me. My LH surge was on CD 17. I usually stop testing once I get a positive result but I noticed my cm is still optimal (egg white) so I tested my LH again. It’s not positive but I think it’s still pretty dark. According to glow my chances of getting pregnant today are 2.1% Based on the test and my cm, what do you all think?
