Cramps at 13 weeks?

Hi all, anyone getting cramps at 13 weeks? They aren’t painful, seem consistent kinda mainly when laying down. It feels like round ligament pain but sometimes like period cramps. I’m not super worried as my doctor said I could cramp my whole pregnancy, also went to the ER when I was 6 weeks for weird cramps and they said the same and what signs to look out for just in case of anything. I figured it’s bc my uterus is growing, constipation, gas, etc etc. I did leave a message for my doctor and hope they call me back tomorrow! Any mamas cramping?
