Generally speaking, the answer is "no." However, it's not as clear-cut as you might think.
Very simply, pregnancy occurs when a male's sperm fertilizes a female's egg. This occurs when a man ejaculates semen, which contains sperm, into a woman's vagina. The sperm then move into the uterus, where they fertilize an egg if they find one. If a man ejaculates into a woman's rectum during anal sex, no pregnancy can occur since human eggs only reside in a woman's reproductive tract.
However, because the anus and the vaginal opening are located close to each other, it's possible – though unlikely -- semen could inadvertently be deposited near the vaginal opening, which could lead to pregnancy. For example, if a man ejaculates outside the rectum during anal sex, the semen could be deposited on the woman's vulva (the outer area of the vagina). If any of this semen made its way into the vagina, the sperm could possibly make its way into the uterus and fertilize an egg.
However, this scenario is unlikely. The odds of a single sperm fertilizing an egg are low even when semen is deposited directly into the vagina. It's even less likely a sperm residing outside the vagina would be successful.
