Many birth-control pills release a constant amount of synthetic estradiols and progesterone for 21 days, followed by 7 days when no hormones are ingested. Which of the following statements MOST accurately describes the effects of birth-control pills? Birth-control pills maintain constant levels of estrogens and/or progesterones and mask the release of the oocyte from the follicle. Birth-control pills maintain constant levels of estrogens and/or progesterone so there is no surge in LH and ovulation does not occur. Birth-control pills inhibit the development of the uterine lining so implantation of a fertilized oocyte cannot occur. The 7 days with no hormones does not allow a thick enough uterine lining to form so a fertilized oocyte cannot implant.

While some birth controls are different, the most common prevent the egg of the month from dropping into the oviduct by releasing chemicals into a woman's body. You must take pills for a month before this takes place. You will still have your period.
