– Risks are present whether the estrogen is delivered into the blood stream with pills, a patch, an injection, or a vaginal ring contraceptive. The risk is highest when first starting these prescriptions.

Why does estrogen-based conceptive use increase the risk of blood clots?

– Hormonal changes can cause blood cells to bind together more readily.

– Taking estrogen contraceptives can increase risks if you have other risk factors such as:

  • Inherited blood-clotting disorders
  • Family history of blood clots
  • Surgery
  • Obesity
  • Prolonged travel
