I know I didn't have a wet dream!

Nor did I pee on myself?! I woke up to VERY wet underwear and I also could wake up before I actually woke all the way up and feel wetness thinking maybe AF had come even tho I just got off a week and half ago. I know I just ovulated due to taking a kit and also my calendar. But I only BD once this week. Well last week a day before O started. What's going on? Anyone else had this
