"The morning-after pill — a form of emergency birth control — is used to prevent a woman from becoming pregnant after she has had unprotected vaginal intercourse. Morning-after pills are generally considered safe, but many women are unaware that they exist. Here's how the morning-after pill works.
Human conception rarely occurs immediately after intercourse. Instead, it occurs as long as several days later, after ovulation. During the time between intercourse and conception, sperm continue to travel through the fallopian tube until the egg appears. So taking emergency birth control the "morning after" isn't too late to prevent pregnancy.
The active ingredients in morning-after pills are similar to those in birth control pills, except in higher doses. Some morning-after pills contain only one hormone, progestin (Plan B), and others contain two, progestin and estrogen. Progestin prevents the sperm from reaching the egg and keeps a fertilized egg from attaching to the wall of the uterus (implantation). Estrogen stops the ovaries from releasing eggs (ovulation) that can be fertilized by sperm.
The morning-after pill is designed to be taken within 72 hours of intercourse with a second dose taken 12 hours later. Side effects may include nausea, vomiting, abdominal pain, fatigue and headache. According to the Food and Drug Administration, the morning-after pill is 80 percent effective in preventing pregnancy after a single act of unprotected sex.
Morning-after pills aren't the same thing as the so-called abortion pill, or mifepristone (Mifeprex). Emergency contraceptive pills prevent pregnancy. The abortion pill terminates an established pregnancy — one that has attached to the uterine wall and has already begun to develop.
Plan B is available to women 18 years and older without a prescription at most pharmacies. Women must show proof of age to purchase Plan B. For women 17 years old and younger, Plan B is available with a doctor's prescription."

Community provider? This is a funny story, proper? If that is within the United States, then your instructor has dedicated a quantity of crimes already. And you're complicit. If you are beneath 18, he can also be charged with generating and owning baby pornography, that is a significant criminal. As to confronting your instructor, his crook conduct offers you the possibility to blackmail him for an A within the direction. Are you a blackmailer? Can you appear your self within the replicate within the morning with out feeling like a average crook? My advice is to position this sordid episode at the back of you and act as though it on no account occurred. There isn't any manner that you'll be able to make it appear well on a resume. The simplest group provider that you just supplied was once on your instructor's libido. You would say that you just did after university modeling, however whomever you inform this to will wish to peer your portfolio. Are there any photographs that may not be a legal responsibility to you?

It's basically the same thing they put in birth control pills just a massive dose at one time so with in like 24-48 hours of intercourse it "fools" your body into thinking it's already pregnant there for if conception did occur your body would reject it thinking it was already pregnant. At least thats what I recall from my A&P class a few years back... :-)

It works by making the condition of the uterus less likely to have an ovum attach. This is done by the hormones of the day after pill. You could become nauseous due to high amount of hormone you just put into your body.
