Nervous

SLS

I'm late by 1 day! But yesterday and today I have been spotting brownish/pinkish blood very light but no full on period.. idk way to do but my tests are negative. Should I go to Dr for blood test or do u think I'm cycle is coming on.. S/N: I'm never late this has never happened.. no stressing but I am having that discharge I mentioned above but only when I wipe.. nothing on my pad also having bad back pain
