lol about DH using the thermometer after V-temping. My DH knows if it is in the bedroom or bathroom (where I sometimes leave it after reading it there in the morning) don't touch it!

I agree with JM though, it does look like an O dip. Watch your temps over the next 3-4 days for a better indication. Maybe your surge was only short and came last night. How did you take you temp today? Don't change to V-temping until the next cycle. I stupidly changed part way through a cycle and so I can't trust the chart that month.
