Hi there
Welcome. I'm so sorry you have a reason to join us here.
What to do is a personal choice. Some ladies prefer the D&C as they are able to "get it over with", so to speak, and move on to begin healing. Other ladies prefer to let nature takes its course and go the natural route.
The decision is ultimately for you and your SO to make. What is right for one isn't always right for another.
Big ((hugs)) to you
