There is not one that I know of. However, the good thing about the morning after pill (Emergency Contraceptives) is that they are out of your system within about 24 hours. They can cause some irregular bleeding or effect your period but they are actually quite safe. Obviously they shouldn't be used all the time like birth control but occassionally they are fine. Also, the type you use makes a difference. The easiest are Progestin only. Less side effects such as nausea, etc. Plan B is a popular brand which is just 2 pills.
