ovulation update

Nikki

so I have had this app for less than a month so far so good. This has predicted my most peak fertile time was the weekend 1st 2nd October. but during this first cycle I have marked down that I have taken 3 ovulation sticks which have all come back negative during this cycle. I have noticed tonight this app has predicted that now my fertile day is at peak for today. I'm now a little confused can anyone help me?? x
