Pregnancy cramping

Kr

Hello to all the mothers or currently pregnant ladies. So I found out I was pregnant 3 weeks ago. Since then Ive been having period like cramps in the abdomen from mild to severe. Does anybody else experience that?

I went to emergency to get checked but I was told Im okay but the cramps could either be future misscarriage or just a normal pregnancy cramps. So Im kinda worried. Did anybody else experience cramps in early pregnancy?
