Did I miss my O this month?

Lindy • Happily married since Dec 2012. TTC #1 since Feb 2014. Found out on 6/13/14 that I am due 2/15/15. We are overjoyed!
This is our first month TTC and My period stopped on 3/16. The top test I took on 3/20. The bottom test I took this morning. Since the bottom test is so much lighter (there is one there), did I miss my O? According to Ovia, I'm supposed to O on 3/26. Maybe testing at 9am is too early? ​​
