Should I have waited misdiagnosed

I feel I was misdiagnosed for an ectopic they assumed 6weeks 6 days but hcg level shows this they also assumed ectopic three weeks later levels rise and forced me to do the shot again and or have surgery they admitted me a few days to monitor me they also gave shot again. I felt like I was killing my baby that wanted to live smh my heart bleeds I feel that I was earlier then assumed and we should of waited would anything should of been seen on tvu at this level :(

How they diagnosed me but didn’t know

Are doctors aloud to presume ectopic/medical diagnosis
