Advice please!

I'm now 10 days late and have no symptoms/signs of AF showing up. I tested twice (Last Monday and last Thursday) and both were negative with no faint lines. I'm contemplating testing again tomorrow. Advice? Should I test again or wait it out a few more days? I've never been late other than when I had a cyst burst one month. I've always been 28-29 day cycle and right now I'm on 38 days.
