Any thoughts!?

Glow says I am 10 days late. My last period was June 11th, lasted 5 days and was pretty normal for me. I'm not sure if I ovulated though as I didn't use opks. As of yesterday I started to cramp a little, stomach was tender and I'm having ewcm. Does this mean af is finally coming? Last time I took a test was Thursday last week and it was negative.
