I think your o date is probably right. Even with the open circles you can see a temp shift. It could be a little off but you definitely look like you ovulated. You should start charting your cervical fluid too. This will help to have something to look at if you have issues with your temps. I think you could have gotten pregnant this cycle but it doesn't look like you bd'd very close to your ovulation day. It is still possible but your chances would be better if you timed things a little closer.
I have gotten to where I try to not skip more than two days in a row of bding. Dh isn't always cooperative though. I have gotten pregnant before several days out from ovulation so I wouldn't say you were out but it would have been better if you could have gotten one more day in around your o date.
Good luck and lots of baby dust! Stick around. I need some more charts to stare at.
