Scared of ectopic pregnancy

Had a scan today which I thought I was 6 weeks and a few days . Mr dr was doing the scan early due to lower progesterone early on. I’ve been on supplements and my progesterone has risen.. my hcg went from 44 Feb 1, 913 Feb 9 and 3300 on Feb 14 so they are rising pretty good but todays scan showed nothing. My dr couldn’t locate anything.. now I am praying that it’s just a bit too early and we just couldn’t get a good read going for another ultrasound Tuesday . But now that ectopic has been mentioned as a possibility I’m am just heartbroken and scared .. idk what to feel. I thought I was finally feeling pregnant these past few days but now idk what to think
