13 weeks 3 days pregnant flutter feeling?

I woke up this morning at like 5 and had a fluttering feeling in my stomach it kinda freaked me out cause I couldn't get it to go away! I don't know If this has anything to do with the pregnancy or of it's something else.... My stomach hasn't felt this way before I thought maybe it was stretching or maybe I was just hungry lol. Any feedback is helpful.
