i use FF to keep track of my cycle days too. I haven't recorded any temps on there though.
I have used tons of OPK test strips though. I've never even had a second line, let alone a positive OPK. My body doesn't produce LH hormone
the digital ovulation tests are a bit more sensitive. I never get a true positive with OPKs, I get a second line that's a bit darker than my normal line but I confirm with the digi one. Amazon do a subscribe and save option never thought that I would be buying that as part of my monthly supplies
