What do you think of the new FDA approved "ella" 5 day emergency contraceptive pill?

The extra two days it allows for is good, but I do find it concerning that it works by blocking progesterone, (i.e, the same way RU-486 pills work) due to the possibility of misuse, which could be really dangerous

also, from what I can find online, it prevents 60% of pregnancies, which is an improvement, but if you took it, and still ended up pregnant, I would be concerned about the effect the lack of progesterone would have on both the mother and baby. For example, a lot of work is done in our labs on lack of progesterone resulting in post-partem depression.

What i dont quite understand is that the whole argument behind plan b was that it did not terminate a pregnancy it prevented one since it had to be taken by 72 hours. If you can take it up to a week later now, the egg has already fertilizied the sperm so a pregnancy has already started so this pill would be an early ab.ortion pill. I am pro-choice, but i feel there should be a little more involved in terminating a pregnancy than going to pharmacy and simply buying a pill.
