Could I be pregnant?

Sami

So my boyfriend and I have been having unprotected sex and he’s been finishing inside me, I’m on the Depo shot, I’ve only had one injection and I’m not getting anymore. I’ve been feeling nauseous when I eat or smell certain foods, it feels like I’m getting small cramps, and today my boobs started to feel a little sensitive. Could I possibly be pregnant? We’re planning on going to a clinic on Friday to take a pregnancy test, but I need more opinions 😅
