Ovulation tests

Elizabeth • Boy mama x 2

Hey all! So I’ve been tracking my cycle closely this month with clear blue digital tests and also the cheap line tests. I got my peak on clear blue Sunday evening but my line test didn’t look positive. Then the next few days I was low fertility on clear blue but my line tests were positive. Has this happened to anyone? I would think it would all match and sync up and it doesn’t. Thoughts?

Thanks!
