Has anyone ever had a late period (5+ days), got negative pregnancy tests on multiple days, and still ended up being pregnant?

I am 6 days late. My period was expected on the 13th. My last period was September 12th. I have NEVER missed a period since I started having periods. I also have never went without experiencing multiple PMS symptoms like cramping, acne, sore breast, but this month I have no symptoms. However, I did find myself very sleepy for several days and feeling under the weather (sore throat). I took tests yesterday morning and this evening. A line test and digital test, both negative. I don’t know whether to chop it up as a random missed period or still have hope. I’m so irritated I don’t want to see another negative test 😒 .....help 😩
