I am past the point of needing this but if I were a young woman, I would be interested in knowing this? Having studied biology, I know there is a point before the egg and sperm get together and start forming a baby. I am of the opinion that this medication just makes the environment for conception to be not condusive to that effect. I think that this though frowned upon by some is much a lessor problem than having an abortion, which I don't like the thought of. I also wonder what the side affects for these pills are on the woman. Are there any dangers? These pills are nothing like the abortion pills they have in other countries, right?
