By what method do women typically terminate a pregnancy at 6 weeks in the U.S.?

At 6 weeks gestation, the most common method for terminating a pregnancy in the U.S. is through medications. This method involves the use of Mifepristone (often referred to as the abortion pill) followed by Misoprostol, which together induce a miscarriage.

Vacuum aspiration, while a common procedure for terminating pregnancies, is typically performed later in the first trimester or second trimester, rather than at such an early stage. Dilation and curettage (D&C) is a surgical procedure often used in various gynecological procedures, including miscarriage management, but it's not the standard method used at 6 weeks. In-clinic procedures can be a general term and include various types of abortion methods, but they also tend to be utilized at later stages of pregnancy.

Therefore, while vacuum aspiration is a recognized procedure, the medication method is preferred and widely used for terminating early pregnancies at around 6 weeks gestation, making it the correct choice in this context.
