Cramping normal?

I am 4 weeks and 5 days. I found out I was pregnant about a week or so ago. About 4 days before my period. And the past 4-5 days I’ve been cramping a lot on and off. I know it’s normal to cramp, and although it’s not severe pain, I’m still worried bc it just seems like a lot more than what I’ve heard others. And they feel like mentrual cramping. I don’t have any bleeding. They last a minute or two and I get them a lot through out the day. It feels like my right side is cramping a bit more than the left but it’s mostly in the middle. Its what I assume everyone means by the stretching and pulling feeling. I’m just really worried about ectopic pregnancy. Can you guys please tell me what your cramping was like in your early days of pregnancy?? I just don’t know what’s normal and what’s not
