So sorry for your loss.
I'm Adrienne (32), and DH is William (31), and we're in our fourth cycle of TTC #1 after an early loss last cycle.
My loss was sooner than yours, and my hCG dropped quickly. It was back to zero within a week of the m/c. So we decided not to wait a cycle. I know exactly when I ovulated, so dating the pregnancy (knock on wood) won't be a problem for us.
It sounds like your body is getting back to normal quickly, but you'll know emotionally when you're ready to start again. Good luck to you.
