15 weeks cramping

Wondering if anyone is having mild cramping in lower abdomen at 15 weeks pregnant. I’ve been having full aches, pains at times and sometimes cramping. Is this all just normal “growing pains” or round ligament pain? It has just been an uncomfortable feeling that has also made me feel restless at night and is making me have a hard time sleeping. Anyone else having these feelings? Doc said it normal and round ligament pain. Just looking for some reassurance that others are feeling these feelings as a first time mom whose always worrying.

Thanks!
