I provide a graphic description, which comes directly from Planned Parenthood, because everyone needs to know what happens. "First, you take mifepristone. This pill stops the pregnancy from growing. Most people don’t feel anything after taking the mifepristone. The second medicine is misoprostol. You’ll either take the misoprostol right away, or up to 48 hours after you take the first pill — your doctor or nurse will let you know how and when to take it. This medicine causes cramping and bleeding that empties your uterus. The pregnancy tissue will come out through your vagina."
This is not headache medicine.
