Watery discharge

So the past couple of days I've had heavy clear watery discharge. I was standing in line at the store (wearing a dress) and felt something and ran out thinking it was my period. Now it just keeps happening haha. It's just clear and super watery almost looks and feels like I peed myself. I'm on the last day of my "fertile week" and every opk test I took was negative. Who the heck knows.
