Anyone use this and it work. My profile tells me ovulation is June 7th through 11th then the calender tells me ovulation is June 10th - 14th ... I'm confused

    I'm sorry, I don't use that one, but it sounds like it could be a hiccup in the app programming--maybe submit a ticket to them?
      8Theresa Gould many days before and after are you counting compared to the profile? I usually count at least three days before (sperm can live up to 72 hours inside us) and three days after the actual "O" day. Just to be sure.
