Ovulation or pregnant?

My period just ended yesterday and today started my fertile window. The night before last I was having a dream I got shot in the stomach three times.(weird, I know.) I woke up with a stomach ache and it's still hurting today. I normally can feel my ovulation cramps but this is early and much more intense. We did BD on Sunday and Monday (edit:AND Tuesday). Is it crazy to think that this is a very early sign of pregnancy?!
