Are my hcg levels normal?

I went to the er around 2 because I was spotting and having bad cramps. They confirmed my pregnancy with a test but the dr was worried it might be an eptopic pregnancy (which can kill me) so they transferred me to the big hospital for ultrasounds. And They couldn't find the gastranteotal sac however you spell it. So they did blood work and my hcg levels are at Least 116 which is kind of low. So this means I'm either too early for the ultrasound to pick anything up (if my hcg levels double in 48 hours than that is most likely the case) if the levels get lower it means I'm going to miscarry soon or I am now, and if they get higher but the sac still can't be found, it implanted itself into my Fallopian tube and I'll have to have surgery or else it will burst and I will hemorrhage and bleed to death. I’m also only 14-15 DPO so I’m praying very hard that I’m still early and that my hcg levels are normal and they will find the sac the further along I get. I’m not longer cramping or bleeding and the cramping and bleeding I was having was not too bad or painful. I just went to get checked out because I got worried. Any advice? What were y’all original hcg levels when you first found out? Did anyone else have trouble finding the sac?!
