Please can someone help me with my chart?

Hi Girls, I finally got crosshairs today but I think it might be wrong. I think I ovulated then (I don't do OPKs) but can't be sure. I didn't go to bed until 2am then was up every 30 minutes or so. I finally fell asleep around 6am and took my temperature at 7.15 which is 45 minutes later than usual. Do you think I wait and see what tomorrow's temp does and maybe discard today's? I don't want to leave it there and have actually missed O!

 

I tried sticking in a few temperatures for tomorrow and Monday. If I discard today's it still says the same day for O

 

This morning I discarded yesterday's temperature and still got my crosshairs on the same day I'm just hoping that the BDing that we did was enough!
