Day 16 of my normally 35 day cycle. Doing OPK tests at the same time each day since day 10... Yesterday I had a very faint line. Today this (see attached pic). What your thoughts? I read that you ovulate 24-48hrs after the test comes back +... And the line needs to be as dark as the test line (test line left in pic). Is this a bit fainter? Mwah ladies! Happy baby dust in the new year!
