Pregnancy occurs when semen enters the vagina and fertilizes an egg, and then only. If no semen entered your vagina (or the area outside your vagina, since sperm can swim), there is no chance you can get pregnant. The only way this would be possible during oral sex would be if the male had semen present on his mouth before it came in contact with your vagina.
There are no harmful effects of sex during pregnancy.
