Hello, I'm Currently About 8 Days Late For My Period,

Hello, I'm currently about 8 days late for my period, even though my cycles are irregular sometimes. I've had an extremely increased vaginal discharge and menstrual like cramps for the last few days. I have taken a test 2 days ago and it was negative. Is there still some hope? I do have pcos and have been ttc for about 2-3 years now. Thanks!
