Possible Pregnancy

Tanzania
According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, my period is 4 days late. I've spotted a little and now the spotting is gone. I think I may just be stressing but this happened with my last pregnancy as well. Last week I had major cramping to where I ended up at the doctors office and now they want to give me an ultra sound. Am I pregnant or nah?
