Need help. .am i pregnant?

Since Sept 21 I've had my BC out(nuvaring) and been having sex on my fertile days and checking my cm took a pregnancy test in the am on Saturday and it was negative. Idk if its too early cuz my period is due Oct 19 and my last period was 5 days late and was light for 3 days and gone. Please help! I'm going baby fever crazy!
