Understanding the Two Medications
Mifepristone: The First Medication
Mifepristone blocks progesterone, a hormone your body needs to continue a pregnancy. Without progesterone, the pregnancy cannot continue to grow.
Misoprostol: The Second Medication
Misoprostol causes your uterus to contract and empty, similar to what happens during a miscarriage.
What to Expect: Timing Varies
Timing varies—and that's normal!
While most people experience cramping and bleeding within the first few hours after taking misoprostol, it's completely normal for the process to take up to 24 hours. Some people pass the pregnancy quickly, while others take longer. Both experiences are normal.
