Implantation or ovulation bleeding ?? HELP

Charity

So I missed my period the month of July. It was suppose to come on round the first of July . So i missed a WHOLE MONTH of my period. August came and my period came on round the 1st. It lasted 5 days ( my typical normal period) .. 7 days after i began spotting light pink discharge , a little cramping , and nausea and i had slight sharp pain in my lower abdomen time to time. It lasted 3 days. I’m so confused on what’s going on? Is this implantation? Etc
