HCG levels after D&C

I had a D&C 2 weeks ago on August 11th. Our baby stopped growing right around 10 weeks and my procedure was done when I would have been 11 weeks 1 day. Just curious how long it took everyone’s hCG levels to go all the way down. I have my 2 week follow up tomorrow and will get a blood draw but I feel like my tests are still kind of dark.. or just darker than I hoped they would be. My husband and I had to do

IUI

to get pregnant so now we will just be waiting for my period to start so we can do another

IUI

..

This is my test from today 8/25. It’s definitely a lot lighter but still an obvious positive.
