Frustrated

Heather
Ovulation testing is so frustrating. Yesterday I got my "peak fertility" on a clear blue digital advanced test but a negative on my strip test. I can't use the digital for 2 days but today got a positive on my strip. We BD last night and will again tonight or early tomorrow to be sure but it's crazy that different tests give different results. I'm also only on cycle day 12 and my cycles have been ranging from 28-33 days so it just seems early to be ovulating. Anyone else experience this?!
