Excessive watery discharge when sleeping

So for the past month or two, I have been producing mainly watery cm, with a few days of creamy cm here and there. And for the past three or four nights, I have been producing a TON of watery cm when I am sleeping. As in, I am waking up in the middle of the night because it feels like I peed myself. Nothing in my diet has changed, there are no concerning smells that might indicate infection, and I'm not pregnant. Does anyone know why the sudden change? And why so much of it? Please share any knowledge or experience you have with this!
