Hi all ! My husband and I are in month #1 of TTC... I have been using ovulation strips daily to try to better track my ovulation and also try to conceive as quickly as possibly... According to this awesome app I am supposed to be ovulating this Sunday. The strips have been seeming to get darker each day over the past 4 to 5 days, but today as I'm the closest to ovulating , it was a very light negative reading.. I'm still confused about the strips and unsure if I'm understanding it all. Is it supposed to be darker each day leading to ovulation and then be the darkest (positive) on the day of ovulation ?? Also it seems like the app keeps changing my day of ovulation. Originally it predicted to be today and now its saying Sunday. Does the app change this based on the OPK info I'm putting in ? Any help would be appreciated !!! Thank you !!
