An estrogen-free contraceptive is provided which does not have the bleeding-related drawbacks of conventional progestogen-only pills. Thus the invention is a contraceptive kit comprising a combined means for the simultaneous daily administration of a progestogen as the sole contraceptively effective ingredient and an anti-progestogen. Said combined means preferably is in the form of tablets having a normal contraceptive dose of the progestogen and low dose of the anti-progestogen.
