Hi all, just looking for some advice. I’ve been using OPKs this month for the first time. I track my periods on 4 different apps and they’re usually all around the same time. My apps all said I would ovulate on Friday or Saturday. I did an OPK each day in the run up to these days and all were negative until Saturday, which was positive. I used clear blue digital with the pink clip in test sticks and the smiley face. I then did another OPK Sunday, which came back negative but then I did one today out of curiosity and today’s test was positive also. Can anyone enlighten me as to why two positive days with a negative day in between? Is it sensible to today’s test was a false positive? Or yesterday’s test was a false negative?
Thanks in advance.
