I think I'm pregnant!!!

So i was incarcerated for almost 4 years...... Had sex the first week I was home told I was pregnant last month but my cycle came on. This this month my cycle is 2 days late. Then my Aunt asked me yesterday was I pregnant and everytime she ask something like that she's always right. What should I do just wait a little longer or take a test. I have been nausea and eating every couple of hours and taking nap during the day.... I have been really tired from not doing anything it's so wierd
