Oral Contraceptives: Side Effects & Pregnancy Risks You Need to Know


“Rates of unintended pregnancies are particularly high in young women, a finding that may be associated with their tendency not to use contraceptives correctly and/or consistently. For millennial women, busy lifestyles and associated stress may impact on daily activities, including taking an oral contraceptive pill.” — National Library of Medicine


No contraceptive method is foolproof. If you think you may be unexpectedly pregnant, make an appointment today. All of Sira's services are available at no cost to you.


How Effective Are Oral Contraceptives at Preventing Pregnancy? 

There are two types: the combined oral pill and the progestin-only pill. The combined oral contraceptive contains the hormones progestin and estrogen, whereas the progestin-only pill contains just one hormone (progestin). For better efficacy, it is usually advised that the daily dose is taken at the same time each day. Both options have a 7% failure rate when used consistently and correctly on a daily basis. 


However, according to the National Library of Medicine, 39% percent of surveyed participants had forgotten to take their contraceptive pill at least once in the past month; 39% also admitted not taking it at the same time each day. This means the failure rate increases exponentially. 


What Are the Most Common Side Effects of Oral Contraceptives?

Oral contraceptives do not protect against STDs and should be avoided in women who smoke or have a history of blood clots. They are also classified as group 1 carcinogens and can increase your cancer risk. Side effects vary by the type of hormone method, but common side effects for these methods include, but are not limited to:

  • Blood Clots (some women are at a high risk)

  • Depression, Anxiety, and Mood Changes

  • Excessive Body and Facial Hair

  • Forgetfulness or Memory Loss

  • Blacking Out and Fainting

  • Muscle Weakness

  • Breakouts, Acne, and Hives

  • Gout

  • Hot Flashes and Hormonal Imbalances

  • Insomnia or Unexplained Tiredness

  • Weight Gain

  • Decreased Libido

  • Miscarriage
