I miscarried around 5 years ago, at around 6 weeks too. I never grieved over it. It was early, I had only found out I was pregnant a few weeks before the miscarraige, so I hadn't even had time to get used to the idea of being pregnant. The only time I even think about it now is when I'm being asked my preg history at the doctors. So if you don't ever grieve over it, I'm sure that's pretty normal. I also lost a baby who was 3 weeks old, and the miscarraige and losing my baby were not even comparable to me, but I do know people who have miscarried and it's affected them like losing a child.
I hope your d & c goes well, my sister just had one last week (idiot dr's who delivered her baby a few weeks ago apparently didn't notice they missed a piece of placenta and she got an infection).She was back home taking care of her kids in a few days, so hopefully you'll feel up to chasing your toddler soon.
