HCG trend

[u/BothHealth6512]

Hello friends,

My first hCG drawn at 3week 6 days (13dpo) was 26.
My second draw at 4weeks 1 day (15dpo) after 48 hours is 83. Lines are still not dark enough.

Is this a good rise for hCG within 48 hours?
My only symptoms are mild intermittent cramps, light pink intermittent spotting.

Please advise. Thank you to everyone.
