Has anyone ever had an almost positive OPK test and then it went back down without ever fully getting positive first? Did it come back up eventually and you got your positive?

This just happened to me on Cycle Day 8 and I haven’t had this before or heard anything about this. No PCOS or any other problems. I’m a gradual onset, my rise happens over a 3-4 day period so it would be darn near impossible to miss unlike a rapid onset rise. I have been testing 2x a day though.
