Pregnant with endometriosis/ past ectopic

Hey ladies. I’m 4 weeks 5 days pregnant and my cramps have been pretty intense. I’ve also had a lot of back pain/ leg aches. My Dr didn’t seem too concerned even though I’ve had an ectopic pregnancy before. Just wondering if you have experienced this when pregnant with endo? Thank you for any peace of mind for me during the next 2 weeks while I wait for my ultrasound.
