At-home urine pregnancy test assessment after mifepristone and misoprostol for undesired pregnancy of unknown location.

Objectives: The ideal assessment after mifepristone and misoprostol for undesired pregnancy of unknown location (PUL) is unknown.

Study Design: We prospectively followed patients at Planned Parenthood League of Massachusetts (2019-2021) with PUL who received immediate mifepristone and misoprostol with serial at-home urine pregnancy tests (UPT) and in-office serum HCGs.

Results: Of 13 patients, 10 had a successful medication abortion.
