Incubus experience, I might be pregnant?

Okay so I had an incubus experience a few months ago and since then, my uterus has been expanding and my stomach has been getting bigger. My period is late, and when I put my hands on my stomach I can feel something moving inside me. Plus, my nipples hurt! Could I be pregnant by an Incubus? Fallen angel? Or could it be a mistaken pregnancy, where you go through the whole cycle but when the time is supposed to come for the babys birth nothing happens? Or when you go through contractions but a baby doesn't come?
