Someone please

So I am on day 4 of just spotting..? It is light pink/brown in color.. I was suppose to start my period 2 days ago.. I am on cycle day 32 of a normal 30 day cycle.. I really don't want to waste to money on a test just for it to be a BFN.. just don't think I can see another negative test. But I don't ever remember spotting for more then a day before many period started. My breast also swell and hurt about 3 days before my period and usually lasts my whole period then goes away, but my breast got tender for like 2 days and then it just went away...
