Cramping normal?

Only 4 weeks pregnant, found out at 3 weeks 3 days. The past few days I’ve had on and off cramping, which I know can be implantation and normal. However, today is the day I officially “missed” my period, and the cramps are worse, actually feeling like period cramps at this point. Is this normal???? I don’t have any bleeding. Any advice please!
