No risk? Nothing comes with no risk, not taking an ibuprofen, not drinking a glass of water from my kitchen sink. However, here's yet another source (http://www.managingcontraception.com/index.php?go=choices&cpage=13), this time from Managing Contraception, that says, "ECPs should not be used as your regular contraceptive. However, if you do use ECPs several times, they are not dangerous." Additionally, one from the Guttmacher Institute (http://www.guttmacher.org/pubs/tgr/05/5/gr050510.html): "Emergency contraception poses no serious risks. It is nontoxic; there is no danger from overdose or potential for addiction; and dosage is the same for all women."

I've asked you for sources a couple of times, and I've looked on my own for support for the idea that emergency contraceptive pills cause harm to the body. In the absence of finding credible medical sources that back up this claim, I'm going to have to conclude that it's not one in line with the facts about EC.
