Cramping in early pregnancy?

Hey everyone! I just found out I’m pregnant and should be about 4w+2d today (confirming it next Thursday!) I’ve been having period like cramps (less severe) for the past three days or so. They’re not bad and only last about 5 seconds. I know it’s not usually a sign of miscarriage but my

question is Could the cramping be a good sign?

I’ve had a fear of having a chemical pregnancy and I’m wondering if this could possibly mean my baby is implanting correctly! Thanks in advance!
