try resting more, sometimes if you experience morning sickness that will deff cause cramps.
I freaked out about it at first too, i talked to my dr. And he said its just stretching. I stopped having them after the first few months.
Yeahh i Googled it and it said its because the uterus growing i just dont know how frequent they should be... but im prob judt over worrying too lol
I freaked out about every cramp everyone explained to me that it's just your body making room
