April 4 -- (HealthDay News) -- Birth control pills contain hormones that prevent the woman's ovaries from releasing eggs -- a process called ovulation.

In many women, the pill causes side effects, which often clear up in two or three months, says Planned Parenthood.

It lists these common side effects of birth control pills:

  • Bleeding between periods.
  • Sore breasts.
  • Nausea and vomiting.
  • Changes in libido.

If you have these side effects for more than three months, consult your doctor, Planned Parenthood advises.
