Hcg levels / ectopic

Hey guys, so the doctors checked my HCG levels to try to rule out an ectopic pregnancy because i’m having shoulder pain. They said it went from 1008 to 2900 within 48 hours. Is that good? This is my first pregnancy and i’m 5 weeks. They said that’s pretty good but they want it to get to 3500 tomorrow. Just want to hear some of you all hcg levels and stories
