OCP: Most hemorrhagic ovarian cysts are corpora lutea, which occur after ovulation. Combination OC (estrogen + progestin) usually suppress ovulation, though not always, esp. with lower estrogen pills. Progestin-only pills do not stop ovulation. OCP are effective contraception because they have other contraceptive effects. SO..."working" depends on why you use the pills. Hope this helps.
