Normal pregnancy vs ectopic

I’ve been so worried about having a ectopic because I’ve had cramps since before I found out I was pregnant and I’m 8 weeks now, nothing has been severe but sometimes I can feel it more on the right side of my lower pelvis (where I ovulated from) but I haven’t had any bleeding or any extreme pain just discomfort. Would you really know if you’re having a ectopic and would you make it to 8 weeks without rupturing? I’m waiting for my first ultrasound
