You can get pregnant if you are having unprotected sex, even if he pulls out before he comes. Because there is also a pre-come wich has sperm in it. Do not have unprotected sex unless you are ready to become a parent.
Even having Sexual intercourse is no Guarantee that the female will become pregnant. However the fact that you ask such a Question, would tend to suggest, that you should not have any physical contact with the opposite sex, until you are at least familiar with the Reproductive organs of both male and female, and how they function. I would suggest you start with the Encyclopdeia of the Human Reproduction System.

Do you mean can you get pregnant from anal sex? No, you can't, if that's what you're asking...
If you have to ask this question, you probably shouldn't be having intercourse. The answer is no. You cannot get pregnant by semen being introduced into your anus. However, your anus is so close to your vagina it is possible for semen to be "accidentally" introduced into the vagina so hopefully you're using protection and plenty of it.
By having sexual intercourse with a man.
When your not having intercourse or when u are using a contraceptive
No. A woman gets pregnant by having sexual intercourse with a man ... or by artificial insemination.
No. You can only get pregnant by having sexual intercourse, where sperm enters the vagina.
Having intercourse while pregnant, does not affect your unborn baby in any way. Intercourse during pregnancy is okay in every way for as long as you are comfortable having sex.

A girl won't get pregnant from not having her period; she may get pregnant from having sexual intercourse. However, the lack of the period may be an indication of pregnancy (but not the cause).
Usually the way you become pregnant is by having intercourse, but it is possible to become pregnant if a man ejaculated, leaving semen in the area outside of your vagina. If your next menstrual cycle is late you should take a pregnancy test.
The anus is usually wider after intercourse, but this returns to normal soon enough. I doubt this is what the doctor cares about though.
