A June 17 Associated Press story – about a bill making its way through the WI Assembly that would ban University of WI health clinics from dispensing or advertising the morning after pill – stated this:

Since the reason pro-lifers oppose MAP is because it may cause early abortions, you’d think the AP would get that critical point right. But investigative reporting is reserved only for those times it might work against conservatives.
If the AP spent five minutes looking into this, it would discover that although MAP makers deny the MAP aborts, they confess:

From Plan B MAP website: “Plan B is believed to act as an emergency contraceptive principally by preventing ovulation or fertilization (by altering tubal transport of sperm and/or ova). In addition, it may inhibit implantation by altering the endometrium” [emphasis mine].

Implantation of what? The embryo. Into what? The uterus.
It takes 5-9 days after fertilization for an embryo to implant in the uterus. Since the 1970s, the pro-abort American Medical Association and Association of Obstetricians and Gynecologists both state pregnancy does not begin until implantation, which is how pro-aborts deceive mothers to think they are not killing their babies when using birth control pills or the morning after pill.
Semantics aside, the embryo is living inside his or her mother during the 5-9 days before s/he implants in the uterus – whether or not pro-aborts say she is pregnant. (See Nova Online 6-minute video, “The first two weeks” to view the miracle of the implantation process. Note the “nonpregnant” woman is called a mother.)
FYI, AP, MAPs may cause week-old embryos to die.
