Based on CF, your OPK, and the temp spike there is a good chance that you did O on CD 22, but one temp does not a pattern make, so your next two temps will really tell us what happened. Hopefully they stay high and get higher. But if they dip back down for a few days then I'd say something else was going on there and to expect another patch of fertile CF coming your way. What was your CF like yesterday? Drier? This would be a good sign as well.
