Pregnant or not?

Mia

My period should've came 6 days ago according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> chart. I had cramps the first coupe of days and even yesterday. But I only had some spotting (very light) last night, and this morning (again very light). Should I take a pregnancy test or wait?
