Faint FRER and corresponding quant hcg levels

While I'm posting this in the inverse as 99.9% of women in this group (watching my levels decrease to indicate a complete SAB and anticipate when my cycle may normalize again) I'm hoping this may be helpful to someone. When I was on the other side searching for quantitative numbers and sensitivity to determine appropriate rate of rise, how early the FRER was picking up the pregnancy, etc I found it difficult to find anything.

Tests were taken 48 hrs apart with SMU followed by a beta hcg quant blood test.

Beta hcg of 5-50 are still considered indeterminate when looking at levels and indicate probable VERY early pregnancy.

Ladies, if you have lines like this keep testing 48 hrs apart. I'm sending baby dust your lines progressively darken and wishing for a happy and healthy pregnancy for you ♥️♥️
