Hi Everyone, I have a question... according to this app as well as my clearblue ovulation test... detected that I was ovulating on June 7th. Now out of curiosity cause of my breast being ultra tender than normal I took the ovulation test again on June 12th and it turned out positive again. Now it was a brand new box of test kits and I checked the expiration date and all is well. Does anyone have an idea why this could be? Please help me... Thank you.
