So Confused- HELP!

Ok, I am TTC and this is my first month using ovulation kits. I bought 2, First Reponse and Digital Clear Blue Easy. I started using the CBE one last week (way early but didn't want to miss my opportunity) yesterday morning, I was getting an error (on the CBE) so I grabbed the FR one and it said I was ovulating... BD! This morning I used the CBE one and it said I was NOT ovulating. I am so stinking confused. Any thoughts or feeback? My husband and I will do the BD just in case...
