Curious

Hey ladies , I had some dull mild cramping on the left side of my lower abdomen felt like it’l was stretching that starting at 6-8 dpo , I’m now 11dpo mild cramping is still there ,took a test today and got a BFN, cycle is not due until 5 more days , should I wait it out or give up? Losing hope since the cramping is the only symptoms I’m having, I normally don’t have any PMS
