Excessive amounts of clear watery discharge.

When I woke up this morning I had so much discharge the bed was wet, and when I stood up it ran down my leg😭 I don't have insurance, I'm kind of worried. This has never happened before, it was clear and really watery. But it was just sooo much, I was supposed to ovulate 4 days ago. Not sure if that's helpful at all🤷‍♀️ Any idea why this happened?
