You can't get pregnant if sperm doesn't come into contact with an egg. That's the good news. Here's the not-so-good news.
Before a man ejaculates, he releases a small amount of pre-ejaculatory fluid. Most guys aren't aware of this when it happens; it doesn't involve the same muscle contractions that lead to ejaculation. Frequently, that pre-ejaculatory fluid contains a small amount of sperm. Sperm can live in the woman's body for 5 days or more.
And (as if that weren't enough) the onset of most women's periods can vary by a day or so, especially when they're younger. Nature does everything it can to produce babies...
Just before your period you are at your most fertile
One in six chances of getting a six

Depends on how far along the woman is in her monthly cycle of menstruation and ovulation. Women are most fertile two days before through two days after they ovulate, which occurs approximately 14 days after their last menstrual cycle. However, sperm has been said to survive up to 72 hours after coitus (sex). Even if a man does not ejaculate (i.e. "pulls out"), sperm is still released during sex, in the form of pre-ejaculate (which occurs during coitus and is virtually undetectable by either partner). Therefore, you CAN get a girl pregnant even if you pull out, and there is a good week or more that she can easily get pregnant out of each month--and that week is actually harder to pin down than just counting calendars.
I have had a partial hysterectomy and had my tubes tied and now I am pregnant what are the statistics
not likely to be pregnant
The chances are great.
It depends if the boy can ejaculate and the girl has started her started periods.
no, not from swallowing though it is possible if it contacted anywhere "down below"

I don't know the exact chances, but it's certainly possible, so you should take a pregnancy test.
Well, the chances of getting pregnant off pre-ejaculate is pretty high considering he doesn't ejaculate inside you. However, it's still sperm so yes you can get pregnant. If she's been proven fertile then obviously the chances rise again, i'd say a fair amount. It would be best to take the morning after pill and make sure to have a pregnancy test. It may cost some money but it's checking all the same.
Yes, there is always a increased chance of getting pregnant when ovulating. When you don't ovulate there is no egg so you can't get pregnant although a orgasm can make you ovulate again.
Call a doctor and ask for a precise answer. If you're interested in common sense, the chances are good enough that you should have demanded he use protection if you didn't want to get pregnant. If your goal was to get pregnant, carry on and quit asking questions - you're overcomplicating it and probably don't deserve to have a child.
If the boy ejaculates after withdrawing it from the vagina the chances of getting pregnant are much lower, but they are not zero, since there are a few sperm in the pre-ejaculate (precum), and she can get pregnant from this. Also, depending on where the sperm lands when he ejaculates makes a difference. If he were to ejaculate onto her belly or back, some could drip into her vagina and, though not as likely, can still cause pregnancy.
You appear to be very confused about how birth control works. It doesn't matter if you've been on birth control for a year if you haven't used it in two weeks. That sex was unprotected. The chances of getting pregnant from pre-ejaculate are lower than if he hadn't pulled out, but they aren't zero. Consider using the morning after pill or other emergency contraception if you've had sex in the last five days. See your health care provider about getting on a method that you can stick with if you don't want to get pregnant.
Zero. You have to indulge in unprotected sexual intercourse. Perhaps you should talk to an adult or read a book about procreation.
