Can you be pregnant with little to no hcg??

I went to the er because I was having abdominal pain my stomach looks pregnant and I have the niagra line if that’s what you call it so they checked my urine which they didn’t recheck the test cuz with the cheapies they take a minute to read and die to settle so I lay on the table get examed and the doctor immediately felt my uterus larger than normal they were not equipped to give me a sonogram so they did a ct scan and told if pregnant and the baby wasn’t big enough they couldn’t see it they checked for fibroids and tumors i have none of that!! So they referred me to a obgyn the doctor said my uterus is not shedding and I only spot when I’m supposed to have a period it’s never on time like it was I’m not the smartest woman in the world but common sense it sounds I’m pregnant just not reading hcg mind you they didn’t bother to check blood even asked if I was poking my belly out just straight humiliated I know I’m not crazy any opinions ???
