Help! What To Do?

Hi ladies!! I need opinions. I'm 14dpo and I've been cramping for a couple of days now, about a week with lower back cramps too.. like AF only not as bad. I tested on Friday (11dpo) and it was negative. Glow says AF is due today. Normally for 2-3 days before AF I get pink/brown spotting. I do not have that. Actually no real CM at all.. just kinda wet feeling. Should I test or wait it out? With the cramps I really feel like AF is coming. I never got any of the normal AF symptoms though, boobs didn't hurt, didn't crave chocolate etc. Could just be a different AF. I'm just nervous to see a BFN :(
