what is it?

So I just took a shower and went to pick up my clothes and put them in the hamper. I noticed on my shorts the were two wet spots on both sides at my crotch but were not connected in the middle, and there was nothing on my underwear. I am confused, it almost smells like menstrual blood but I am not on my period, I was supposed to start it on Monday but it hasn't come yet. I know I am not pregnant because I am not sexually active. This is not water.
