Very clear watery discharge

Hey guys I’ve tried to google it but can’t really find anything that compares to exactly what I’m feeling. My cycle is pretty irregular but I did have unprotected sex multiple times throughout the month. eve says my period is due in 3 days (but again super irregular so this may not be the case) and since last Wednesday I have been getting frequent headaches, nausea, and waking up in the middle of the night feeling super hot. Now since two days ago I’ve gotten a huge increase in vaginal discharge and I’ve never experienced anything like it. I was standing up before my shower last night and it was like dripping down my leg. It keeps feeling like I either peed myself a bit or started my period cause I feel so wet. It’s not sticky at all. It’s very very thin and completely clear. I tested two days ago, but it was negative. Is there still a chance I could be pregnant?
