FDA CONSIDERS ALLOWING MORNING AFTER PILL TO BE SOLD OVER THE COUNTER

[Sundae]

Is it misunderstood to be an abortifacient like Mifepristone?
It's intended to prevent pregnancy, not terminate it, therefore no different than other contraception.

It does not even necessarily affect fertilised eggs - even the drug company information is speculative:

It's still not fully understood how Levonelle One Step® works because it depends on where you are in your cycle. For example:

It may stop an egg being released from the ovary (ovulation)
It may prevent sperm from fertilising any egg that may already have been released
It may stop a fertilised egg from attaching itself to the lining of the womb
