The changes in coagulation parameters were studied in 24 women who started using microdose combined oral contraceptives immediately after first-trimester abortion. Another 24 women who had an intrauterine contraceptive device inserted at the end of the abortion procedure were studied as control subjects. In pill users, a slightly increaed tendency toward hypercoagulability was observed 1 week after abortion in terms of elevated fibrinogen and Factor VIII as well as decreased antithrombin levels. Other studies have shown that the new follicle development after first-trimester abortion starts beyond the first week. It would therefore seem that by postponing oral contraceptive use until 1 week after abortion, no decrease in the effectiveness of contraception occurs and the possible risks of hypercoagulabilty during the postabortal period can be avoided.
