Claire: You had a pulmonary embolism -- a blood clot in your lung. The medication broke it up. Michelle: How did that happen? Melendez: The clot broke off from a larger clot in your leg and travelled up. Claire: As for why the clot formed in your leg in the first place... I asked you if you were taking birth control pills and you said no. Was that the truth? Michelle: You asked me in front of Tisha so I said no. I'm doing it with my boyfriend and I don't want babies so I'm taking birth control pills.
