It's probable that you ovulated! That's what causes your temperture to shoot up.

But, with you getting up at 5:30 to go to the bathroom... that can definitely affect your temp too. 2 hours is generally not enough to get good temp. (You want at least 3, with over 5 hours of sleep being ideal.)
Your next few days will tell if it was because you got up, or if you ovulated.
