Patients were eligible for inclusion if they had undergone a medical abortion with mifepristone\u2013misoprostol at no later than 63 days of pregnancy, had a recorded outcome, and had either started progestin\u2010only contraception immediately after mifepristone administration or had not started contraception. The primary outcome\u2013successful induced abortion\u2013was defined as the complete evacuation of uterine contents without the need for further intervention. A secondary outcome was the number of induced abortions completed without the need for manual vacuum aspiration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Records from 2204 patients were included; 448 (20.3%) patients had started progestin\u2010only contraception, and 1756 (79.7%) had not. Patients not taking progestin\u2010only contraception were significantly more likely to be primigravidas and nulliparous. Medical abortion success did not vary between the two groups; 1890 (85.8%) were successful and 2085 (94.6%) were completed without the need for manual vacuum aspiration.
