Light cramping in early pregnancy can be normal since your uterus is stretching, but it's always better to check with your PD or gynae just to be safe, especially if the cramps are strong or you're worried. I'd say if it's just mild and not accompanied by heavy bleeding, it's likely okay, but there's no harm getting it checked out quickly for your peace of mind.
hey Ain, it is normal but it is also abnormal if you feel sharp continuous pain like menses cramp!
