Choosing a birth control pill

Cons

Here are some possible drawbacks of progestin-only birth control pills:

  • Must be taken at the same time every day. If you skip a pill or take a pill more than three hours late, you need to use a backup form of birth control for at least two days.
  • Don't protect against sexually transmitted infections.
  • Side effects may include irregular menstrual bleeding, ovarian cysts, less sex drive, headache, breast tenderness, acne, weight gain, depression and hirsutism.
  • Slightly higher risk that if pregnancy happens, the fertilized egg will implant outside the uterus. This is called an ectopic pregnancy.
