should I test or wait?

jan 4th was my last period. round out I was pregnant in February, had a chemical, miscarried Feb 6th. bled for 6 days, which is like my normal period just had some clotting & bled heavier for the first 3 days. I was supposed to start period Wednesday (app is saying tmrw, but I think its bc I never documented the miscarriage so it just thinks I started my period late). should I test tomorrow or just wait a few more days?
