Breakthrough Bleeding

Breakthrough bleeding (BTB) is a term applied to various forms of vaginal bleeding, usually referring to mid-cycle bleeding in users of combined oral contraceptives, as attributed to insufficient estrogens. It may also occur with other hormonal contraceptives. Sometimes, breakthrough bleeding is classified as abnormal and thereby as a form of metrorrhagia, and sometimes it is classified as not abnormal.

Famous quotes containing the word bleeding:

    “The wounded surgeon plies the steel
    That questions the distempered part;
    Beneath the bleeding hands we feel
    The sharp compassion of the healer’s art
    Resolving the enigma of the fever chart.”
    —T.S. (Thomas Stearns)
