I've had four m/c's, lost five babies and I've never had a d&c. I've actually fought not to have one done when I lost my twins six weeks apart. My dr at the time (whom is no longer my dr and never will be again) tried to force me to have the d&c when the second twin wouldn't come out. It's a long story but basically I wasn't going to be forced into something I wasn't comfortable with and that I really didn't need just because some jacka$$ dr wanted $$ for a procedure that wasn't necessary.
Having a d&c or not is a very personal thing. With a d&c there is a small risk of scarring in the uterus and a risk I did not want to take. I also treasure the moments I've spent with my children. Even though they were small and didn't even look like babies, I knew they were my children and I've held every one of them. Some women feel differently than I do and a d&c is the way they need to go and there's nothing wrong with that.
As far as our bodies are concerned, about 80% of the time our bodies will m/c naturally and does not need the help of a d&c. To answer your question, No, you did not need a d&c if your body was able to m/c naturally and your beta went back to zero.
