Is it pee or fluid?

I was just standing in the store today and i felt something gush out. I thought it was blood because of the way it felt when I had a period. But i went to the bathroom and it was pee or fluid but im not sure which one. The spot was about the size of a quarter and some clearish discharge came out with it. I havent had any cramping today (sometimes i get a burning cramp in my lower abdomen??) and im not sure what fluid smells like. Im almost 32 weeks. Anyone have any ideas?
