Yay!!! I am so happy for you!
Hmmm with a 2-3 reading/that level... Ctp says 30h to double. So you doubled 6 times to go back to 5-6 hcg which is roughly near implant to 350. Assuming a constant doubling speed that's 180 hours to go from 5 to 350, or 7.5 days. Assuming implant was the average 9dpo then Wednesday was 17dpo, or 4w3d, and Friday was 4w5d. Give or take a few days? Which makes sense if you are about 5w from your d&c, looks like your body bounced right back and ovulated right on schedule around two weeks later
