Boyfriend thinks I’m pregnant

I’m supposed to start my period today or tomorrow but so far haven’t, last week I missed 2 pills and my bf came in me twice within 24 hours. Usually he freaks out and worries himself to death until I start my period, but he’s surprisingly calm and he said today “I’m just gonna call it, you’re pregnant. I can feel it. I’m not worrying this time, it’s like I just know”. Well I’ve been experiencing cramping (but that could be due to my period coming) but I have also been EXTREMELY tired, I fainted at school on Tuesday and had a mental break down and couldn’t stop crying and couldn’t breathe, my back has been hurting a lot, headaches, have felt nauseous but haven’t thrown up, am constantly feeling lightheaded, and I’ve been abnormally hungry lately. Does anyone think my boyfriend could be right? Or is him telling me this just making me question and think I really am pregnant but actually are just about to start my period??
