Miscarriages

An
I just had my second miscarriage at 5 weeks. My hcg levels were measured at 171.5 ok Tuesday, and they'll measure again Monday to see if they're going down. I've been doing pregnancy tests to see if they're going down, and it appears that they're staying the same. They said that would mean that I still have remnants inside me. How would they get that out since I don't have an actual baby to pass since it was only five weeks?
