Digital test help!

I am three days late. Took a clear blue digital test two days ago but said not pregnant. I'm currently on cycle day 39 with no signs of pms. It's a couple days longer than normal.. I'll wait another week to test. Should I use the pink line test instead of digital? Maybe if I am prego, it's not reading my hog. I don't feel prego so I'm not too anxious, but no pms signs either... Thanks!
