An unbroken line of cars stretches ahead of you. You impatiently drum your fingers on the steering wheel, as you inch your way forward through the early morning traffic.

Your phone suddenly rings. You switch it onto "hands free" mode, and answer the call.

"Good morning, Doctor! This is Julie Smith."

You remember Julie, from your fertility clinic. She underwent in-vitro fertilization (IVF) just a few weeks ago.

Julie complains of mild abdominal pain for the last 3 days, which has worsened over time. You tell her that you are on your way to the hospital, and ask her to meet you there.
