Week late, neg test (clearblue took morning of day 5)

Usually right before my period I cramp and have tender breasts. Nothing this time around. So 5 days past AF I took a clearblue test...negative. any chance I tested to early for the hormones to come through? I am now 8 days late. I have had a child before so while I am having some cramping, it's been lower (somewhat cervix area) which I remember from when I was pregnant with my daughter that I had that discomfort sometimes. Anyways...no normal cramping, I'm very tired and wore out, my breasts aren't sore but again they weren't with my first until after she was born and I started breastfeeding. I know typically no two pregnancies are the same and seeing as we are ttc I am sure I was over-analyze it until I get a BFP or AF shows up.
