Does plan b prevent a fertilized egg from implanting?
A doctor has provided 1 answer
Plan B: Plan b one-step works like other birth control pills to prevent pregnancy. The drug acts primarily by stopping the release of an egg from the ovary. It may prevent a sperm from fertilizing the egg. If fertilization does occur, Plan B one-step may prevent a fertilized egg from attaching to the womb.
