The morning after pill is a pill that is used after intercourse and alters the menstrual cycle, thus not letting fertilizing and/or implantation in the uterus to occur. Once fertilization and implantation occurs, abortion is the only way. Dilation and curettage, in this case, is also considered as an abortion.


The ovulation occurs exactly fourteen days before the start of the next period, which can be only assumed and not calculated for sure when having intercourse, at least until the next period actually starts. So, one week after the end of the period might include the ovulation day if the menstrual cycle is short enough, and using other more secure ways of avoiding pregnancy is recommended.
