Discharge or........?

An
For the last two days now I have had this clear liquid come out "downstairs" It's not distcharge and I feels like and is as runny as water. There is a odor to it. I have never had this happen before and quite frankly don't know what it is. I have to constantly change my pantiliner. The first time it happened it stoked through my panties and onto my jeans. It feels like I am constantly peeling a little thought the day. Advise anyone?
