Does birth control cause blood clots?

Using a method of birth control with estrogen increases a young woman’s risk of forming a blood clot by several times, but for women who have no history of stroke, blood clots, or heart attack, and whose family members have never experienced a blood clot, the risk is still quite low. Women with a history of these medical conditions in their family have a higher risk of forming a new blood clot; adding birth control with estrogen to the mix increases that risk to an unacceptable level. 

Progestin-only methods like the implant, mini-pill, the shot, and Skyla and Mirena IUDs don’t increase your risk. If you’re worried about blood clots, we recommend talking to your doctor about which birth control options are best for you.
