HCG levels

I have a question about my HCG levels if there's anyone that can help me.

This was my first month of ferema after my miscarriage March 26th. I'm on metformin to help keep everything normal.

On Friday May 26 I went in for progesterone test and the clinic accidently did an old HCG test left over from my miscarriage. My progesterone came back at 58.5 at 10DPO and HCG was 2. Sunday morning I did a test and it was positive, so I went back for HCG blood work Monday May 29 and my blood came back at 59 at 13DPO.

Is that a good level, it seems low to me and I'm having a hard time trying not to stress about it.

Whats a good number for 13DPO?

I have one more blood work tomorrow and Thursday I will be announcing it to the hubby.
