Hi. I'm so stress about if should I take a pregnancy test or wait. My last period came last February 12, 2015, I have irregular periods. Sometimes 28 day cycle and sometimes 31 day cycle and according to the app that tracks my period said that I'm 6 days late on my period now if I have 28 day cycle and 3 days late if I have 31 day cycle. Now, I don't know if should i take a test now or not? By the way I'm experiencing mild menstrual like cramps for about 3 days and last whole week i felt a bit nauseous, belly bloated, always hungry like i just ate but still I want to eat, I once felt heartburn and backache. But still there's no sore breast and spotting. Please help me??
