HCG Levels - Freaking Out

So I got a positive pregnancy test at approximately 10 DPO/CD 28, went in to have my HCG and Progesterone levels checked because I had a chemical 2 months ago.

I went and got my blood work done the next day (11 DPO/CD 29) and my Progesterone was 16.7 and my HCG was 14. I went back 4 days later to get my HCG tested again (15 DPO/CD 33) and the results came back at 32. So my levels went up but I don't think they've gone up the way they should. I'm going back today, 2 days since the last test (17 DPO/CD 35) to get them done again.

Of course the nurse I spoke with that gave me the results didn't indicate one way or another what her or the doctors thoughts were.

I AM FREAKING OUT!!! I don't want someone to reassure me because surely my mom and husband will do that (haha) but if anyone has gone through something similar or has knowledge/insight on the topic please share!
