help?

I went to the doctor with abdominal pain for about four weeks, surprise, I'm pregnant! Exciting and terrifying because the pain as I described it can be abnormal and mean an ectopic pregnancy.. I told the doctor I had some spotting just before my doctor appt and she said it's normal. But now they're closed and it's still happening and the cramps are stopping me in my tracks to catch my breath. They only do ultrasounds thursdays so I got the only appt Thursday that I could get. I'm not sure if I'm just too nervous and overthinking things... My doctor told me only to really be concerned if it physically felt like my uterus was coming out of my abdomen kind of pain.. But I don't feel like constant cramping like I'm on my period(which I have endometriosis so my period cramps are BAD.) is normal in early pregnancy? Is it? Like constant?
