6 days late and lots of discharge

6 days late and an excessive amount or water/white discharge??? I’m so confused I’ve took numerous tests and all negative I just wish I knew what was happening! It’s driving me crazy I think I might have ovulated a little later than when I was supposed to could that honestly be the reason I’m not getting a positive ? Could I still be pregnant??? Any one who had went through this and actually been pregnant ? I’m just worried I’m pregnant but I’ll miscarry or something
