Postitive opk 4 days in a row

Serena
Hi guys i thought it would be best to ask my question here but i finished my period about 4 days ago with very light spotting. I took a clearblue digital opk test and came back positive. I took one today as well and it came back positive. Is this normal or should i be concerned? Not sure if to take a pregnancy test or try another opk test tomorrow?
