17 days of bleeding

Ok so please ex use me because I do not know any of the terms yall are using. Okay here's my story. I've been bleeding(spotting) for the past 17 days. It started a day after my ovulation period. My period was suppose to start Nov 1. Since I was bleeding I'm not sure if it's my period or not. I took a test a couple of days before my period was suppose to start and took one 5 days later on the day it was suppose to start. Both test came back negative. I'm still bleeding and it's been 4 days since I took the last test so should I be concerned or what. My husband and I have being try for 4 years and no luck. I also have pcos but my cycle has been regular for the past couple years
