Cramping at 4 weeks

Allie • Mom of 2 girls. Expecting baby #3 in December 2023
I'm 4 weeks and 3 days and I'm experiencing PMS like cramps. Is this normal? I really can't remember with my daughter bc it was 4 years ago but I'm a little worried. The cramps r not strong or intense, no bleeding, just PMS type cramps.
