Help!!! Any idea what this all means?

So this whole experience has been a nightmare. I was thrilled to get a BFP on 11/24, first day of LMP was 10/21. I started spotting on 11/26 and panicked, went to the ER and was told inevitable miscarriage hcg was 1073. Then follow up doctors visit on 12/2 hcg was 1661, I was told it was a threatened miscarriage but since hcg was rising there’s hope. 12/6 hcg 2499, 12/10 hcg 3495. The doctor said he could tell me what was happening since hcg was rising but not doubling until ultrasound. Went this past Friday 12/17 and the tech told me my doctor would call with results, I called the office this morning and he’s left the practice and they don’t have a doctor so won’t be able to tell me what they see until they find a new one and that I should find a new provider, I’ve got an appointment with a new doctor in a different practice on 12/29 but they won’t read the ultrasound until they can see me. I got the result in the picture today but have no clue what I’m reading, other than it seems like there’s no baby and I’ll be miscarrying eventually. I’m devastated and frustrated and just totally lost. Any ideas or input? Anyone?
