9 days late negative test result

Julia

So I’m kind of confused here. I am 9 days late for my period. I am taken a couple of tests and all have been negative the last one was a couple of days ago. I have very regular periods and ovulation cycles. I am having watery discharge minor cramping here and there but my period is no where to be found. Also, I do have regular unprotected sex with my husband. What is going on?
