Miscarriage
Dilation and curettage (D&C).  In a D&C, the cervix is widened, and the tissue left in the uterus is scraped and scooped out ("curettage").  Compared to giving medications, D&C has a higher risk of causing problems.  For example, the cervix or uterus may be injured.  Because of this, some women prefer not to have a D&C because they want to have children in the future and want to lower the chances of problems during future pregnancies.  However, if a woman has had more than one miscarriage, D&C is the most convenient way to get tissue samples, which can be studied to see if a reason for the miscarriages can be found.
