Okay so my boyfriend and I had unprotected sex about a week before my last depot shot ended and I got my new one a few days after. He came inside me and it was the first time anyone's done that. And now I'm kinda freaking out because it's been about a week and my appetite has grown tremendously along with moodiness and I feel like a fat balloon because of how bloated I am. So my question is could I possibly be pregnant? Because of my appetite and weight gain im a little nervous. Please help!
