Help Please !!! Line progression? 12-14dpo

Sam

I got a BFN 11dpo FMU then this BFP 12dpo FMU. Since then each morning with FMU my lines seem the exact same (or maybe slightly lighter?). I am really nervous because I had a chemical 2 months ago, however with that chemical my lines were never this dark.

I am going to get bloods done this morning and don’t know what I should expect my hcg to be with lines this faint.

Any advice/input would be really appreciated! Xx
