Light cramping while pregnant

Lauren
I know for a fact i have a cyst on one of my ovaries. But i won't know details about my cyst until i go back to have it checked on an ultrasound in a week and a half. I have been feeling lightly cramping in the EARLY morning. Around 3 or 4 when i wake up to use the restroom, that's usually when i feel it. And most of the time when i wake back up its gone. I'm also 14 weeks pregnant today. Do you think it could be the cyst or what else could it be? Just worries me
