Unintended pregnancy rates differ according to combined oral contraceptive – results from the INAS-SCORE study.

Yesterday, our latest publication, Unintended pregnancy rates differ according to combined oral contraceptive – results from the INAS-SCORE study was published online in the European Journal of Contraception and Reproductive Health Care.
