Advice needed

What are the chances of me being pregnant. Me and s/o of sex daily no prevention. I explained him my reasons I wanted to go off birth control pills I have never had a normal ish cycle. Mother forced me on the depo shot at 15 right after my first period. From there I had 2 choices when I turned 18 pills or homelessness. But any way I have been super stressed but I'm so nauseous and nothing g taste right. My favorite food sits like a stones in my stomach. Even fruit which I could eat 10 times mu weight in taste awful after a few pieces
