OPK or CM

Jessica • TTC # 1
So this morning I took and OPK that was positive, I didn't see how this was right as I'm only on CD 7. I took two more at the same time (clear blue digital and a $ store cheapie) which both showed no LH surge. The one I took this morning was a $ store cheapie as well. Well I checked CM 3 times today and each time it was EW consistency. I just don't know which I should trust more the tests or my body? TTC can be so confusing. Luckily we did BD 3 times today and I used Pre-seed this morning. Hope this is our month....
