FET 14dpo hcg was 57

Hello there, so i finally got pregnant with IVF. First frozen blastocyst and had bloods done wednesday which was day of period due. My HCG cqme back at 57 and nurse advised that they like to see it around 100 instead. Now i am worried as this is my 10th pregnancy and i only have 1 live birth (my first pregnancy)

I have had a blighted ovum dirst miscarrage and lotsbof chemicals. My last one ended at 13 weeks due to turner syndrome. I guess i am worried this will head in the same direction. What are your thoughts.
