Choosing Your First Birth Control Method

So You’re Interested in Starting Birth Control…

There are many birth control options, and selecting the right one is a personal decision. Some women use birth control not just for contraception but also for heavy menstrual bleeding, to reduce acne, or to reduce the risk of endometrial cancer for those with Polycystic Ovary Syndrome (PCOS). There are a few health reasons to avoid certain birth control options. The following are some highlight discussion points on the most popular birth control methods.

Birth Control Pill

Most women starting birth control for the first time will choose “the pill” because it seems like the most convenient and least invasive option since it does not require a procedure. This is a reasonable approach, but in order for the pill to be reliable, it must be taken consistently. Missed doses reduce the effectiveness of preventing pregnancy. This is the main reason the pill is less effective at preventing pregnancy than other forms of birth control, including the IUD, implant, and Depo-Provera injection. Women who have had a blood clot, have migraines with aura, or smoke and are over 35 years old should not take estrogen-containing birth control pills.


An IUD (Intrauterine Device) is a tiny device that is put into your uterus to prevent pregnancy. There are two main types of IUD’s — those that contain a progesterone hormone, and the hormone-free copper IUD. Hormone-containing IUDs (Mirena, Kyleena, and Liletta) generally stop periods or cause them to become lighter. The copper IUD (called Paraguard) can cause heavier, more painful periods. IUD benefits include:

  • 99% Effective at Preventing Pregnancy
  • Lasts 3 to 10 Years
  • No Need to Remember a Pill Every Day
  • Can Reduce or Stop your Period

Downside: A procedure in the doctor’s office is required to insert the IUD.


The most commonly used birth control implant is the Nexplanon. This is a small (approximately the size of a matchstick) device, inserted just under the skin in the upper arm, that secretes a progesterone hormone. The procedure to insert the implant is simple and performed in a doctor’s clinic. Benefits include:

  • 99% Effective at Preventing Pregnancy
  • Lasts for 3 Years
  • No Need to Remember a Pill Every Day
  • Insertion Procedure is Less Invasive Than the IUD

Downside:  Potential of random spotting.


Depo-Provera is an injectable progesterone-only hormonal birth control that is given as a shot in the arm. The benefits include:

  • 94% Effective at Preventing Pregnancy
  • Effective for 3 Months
  • No Need to Remember a Pill Every Day
  • Periods may Stop
  • Does not Require an Invasive Procedure

Downsides: Depo-Provera is associated with weight gain and you need to come into the clinic every 3 months for another injection (typically given by a nurse).
