Hi Ya'll! First time mommy here

Just a quick question...when I tested positive a couple weeks ago, I went to my doctor and they checked my hcg levels which came back at about 1500 or so. They tested me again about 3 days later, and I was at about 3500. That was about 3 weeks ago...my levels today were at 8252.
Is that "normal"? I thought it was supposed to at least double every 2 days...if that were the case, my number should be much higher. My doctor didn't seem concerned, but it just confuses me...

Here's the link to a table with normal values per week, which you'll see are highly variable: https://www.baby2see.com/preconception/hcg.html
Did they test your progesterone? Was everything fine there?
