Hi My Average Cycle Is 32 I'm 31 Yrs. Old

Hi my average cycle is 32 I'm 31 yrs. old and my menses are normally heavy with clots ..my last menses was April 26 2016 and it was normal ,on May 25 after peeing I wiped and noticed bright red blood so I assumed my period was starting early so I wore a tampon went about my day four hours later I removed tampon and it was dry with the right corner tip showing little blood ..so up until the 28th every time I urinatec and wiped it was pink ...? Is this pregnancy ? I tested it was negative ? I don't have money to pay for an answer
