Edward was able to conceive with Bella because male vampires still produce sperm. There are different types of venom. Only saliva venom can change a human into a vampire. Other types of venom  take the place of human bodily fluids. There's a venom to lubricate the eye leaving it unnecessary for a vampire to produce tears...so they cannot cry. There's venom that takes the place of blood in their veins, venom that lubicates their joints making them incredibly fast. And apparently male vampires are able to sustain an erection. Vampire semen closely resembles human semen....close enough that male vampires can inpregnate human females. However, this doesn't happen often because the human wouldn't live through the sexual process...with the vampire feeding on her.

So.. basicaly... Edward and Bella consumated their marriage, with her getting pregnant. Was this the first time this has happened. No. But most human females would not survive a sexual relationship with a vampire. Edward just didnt' kill Bella.
