Naturally induced miscarriage is the act of using a combination of herbs, vitamins, massage, visualization and prayer to cause the body to miscarry or abort a fetus without mechanical or surgical intervention. The body itself is induced to expel the fetus.
If your measurements are consistent with 7 weeks and there is no heartbeat on two separate ultrasounds, then this is a miscarriage (it is a first-trimester demise) and you and your OB can choose one of three options: 1. Wait for a natural miscarriage 2. Take cytotec to hasten the miscarriage 3. Perform a D&C.
