It's hard to tell because of the open circles you have for temps. Make sure you take them as close to the same time of day as possible for accuracy. There is definitely a good chance you missed your surge with OPK's though. Do you do OPK's a couple of times a day? You should try doing that when you are getting close to O so you don't miss your surge. I suspect the next few days and temps will draw a clearer picture. I hope you O'd!!
