6 days late..

So today I am 6 days late and I’m too nervous to take a test because I’m so sure it’ll be a BFN. My symptoms have been weird. For over a week I’ve had very tender breasts that haven’t lightened up. Also about 5 days ago I had awfully heavy creamy CM. Ive also had very dull period cramps that haven’t gone away so that makes me think I’m about to start. Ive been pretty sleepy more recently too, but that could just be because it’s getting darker earlier lol. What does it sound like to you? Just a late period or should I bite the bullet and take a test?
