Tmi question..gross sorry

Ok so today is the first day off of my green week. We BD all but last night because we BD at like midnight the night before and just to be honest I'm super sore. I have no doubt that the day before yesterday I ovulated..positive test the day before and showed all of the signs.. Ok so here is the tmi..I had to get up and tinkle a lot during the night and then this morning when I got up there was a gush. It soaked my panties. It had NO odor, definitely not urine, clear and was about 4 teaspoons of liquid on my panties. However when I got to the restroom and checked myself nothing came out and everything seemed normal. After a shower the rest of the day is normal besides a bit of a backache for that I give credit to the rain and every few minutes I get cramps in my lower right tummy but nothing too painful. Any clue what that could be?
