Cramping at 14 weeks?

I’ve been cramping on and off today, not bad just a little bit. I woke up with a sharp pain in my uterus but I was sleeping on my stomach, I’m not bleeding at all. Could the cramps just be from the uterus and baby growing and the baby moving around??

I’m not really worried because it’s not intense cramps, but want some suggestions to what it could maybe be.
