no temp shift after peak opk

I usually ovulate on cd14-16. Been using clearblue digital ovulation tests, got my peak reading on sunday (cd13) morning & expected a temp rise on monday morning, but had a (rather unexpected) night out involving booze, so suspect that high temp on cd14 was a result of drinking the previous night. This morning (cd15) i was expecting the rise should have stayed to reflect ov happening, but its back down. I dont know what to think. I've had the static smilie on CB and its still there, does that mean I've maybe not O yet? am I out this month?
