Pelvic vs abdominal cramps?

Jenna • baby boy due March 2019 🧡

I’m 6weeks 3days and most of my cramping has been in my pelvic region. It’s very light and intermittent and I’ve had no spotting or blood but I’m worried that I should be having more abdominal cramps since that’s where the uterus is expanding and stretching. Anyone else?
