What should I do???

Tara

So my period is usually on track with what this app but it was suppose to start last Wednesday on the 31st of July there was some spotting two days before then it stopped then I started spotting again Thursday the 8th of August and still is spotting. Should I take a test since it was suppose to start a week and half ago or should I wait bc of the spotting????? Please any help would be greatly appreciated. Thank you
