clinicalguard opk help?!

Maggi

the line did not become dark, but now it is getting faint again (Not pictured), I've had cramps the past two days, ewcm, and spotted this afternoon which is uncommon for me! we have bd the past three days and I'm going to keep at it until I know for sure 😂 but i would appreciate any thoughts! these tests were super cheap so I'm wondering if they will not become more positive but I'm going to keep testing anyways! I also did not get to take a test at the typical time I do because of work. so maybe I missed my surge if it was short? thanks in advance!
