Just wondering if anyone else has had something similar happen while using clearblue ovulation tests. I've been using them for 3 months now the first two months the tests results were in sync with the period tracker predictions. Both months I only had one day of the flashing smiley face, then solid smiley the next. This month the tests aren't syncing up with my apps predictions and so far I'm on day 3 of the flashing smiley face. The app is saying my ovulation day should of been 3 days ago but the tests are indicating that I haven't reached my peak fertility yet. Anyone had a similar experience?
