Some questions about the morning after pill?

Here are a few questions that I have about the morning after pill that I could not find on when I searched for answers myself:
1: If you take it 72 hours after sex it is effective in preventing pregnancy after intercourse. Is this still true if you have sex say, 2 or 3 times within 72 hours?
2: How long should a woman wait before taking the pill a second time? Is it alright to take it 3-4 times within a span of 2 weeks?
3: What is the percentage of pregnancies if the man uses a condom (no breaks in condom) and spermicide and the woman takes the MAP?
Maybe I should say what are the chances of pregnancy happening if all of those precautions were taken?
4: Is the MAP necessary when a condom is used and they have sex when there is no ovulation... just to be safe?
Then I was also wondering what the percentages of women getting pregnant are when the man uses a condom and spermicide is used as well.

Thank you for your answers!

acatually, I'm a dude, and I'm just asking this because my girlfriend is kindof worried about the having a baby thing and she also feels uncomfortable about going to a doctor to get a percription. Also, she lives in Japan so I'll only be seeing her for 2 weeks. Just exploring the different options

1. Yes.
2. You can take it as often as needed.
3. The percentage of pregnancies if the man uses a condon is about 3% if used correctly and the morning after pill is about 89% effective, no one really knows how effective spermicides are. So the chance of getting pregnant is very very slim, almost none, when using the two together along with a spermicide.
4. The MAP isn't necessary if the condom didn't break or slip of and if it was worn the whole time.

Well, if you are using a condom and spermicide, and both are used properly and the condom does not break, you should be fine. I have done some research on this subject in the past too and I have read in several places that you can take the morning after pill up to five days after intercourse. I wouldn't recommend taking the pill more than once in such a short time considering it is just a really high dose of birth control. Just take it at least within the time limit and after the last time you have sex.

wow all i can say is if you are this worried about having a baby then maybe you should not be having sex.
just get on a birth control pill then you dont have to worry about the MAP

well... you aren't suppose to use MAP as a regular form of birth control... it screws up your menstrual cycle. Here's a site that could answer your questions:
