Please read..really worried!

Alegra

Is this line progression good even though my hcg levels are 22 and progesterone 27? I should be around 3-4 weeks pregnant. The nurse at my OB’s office said my hcg level is low and it’s either really early or gonna be a miscarriage. I am going back to get my levels retested on Wednesday to see if they doubled.

I’m really worried and stressing hard.Top test is from this morning and bottom one is from this evening.
