Twilight fans brace yourselves, a 15-second preview of ‘Breaking Dawn: Part One’ has been released in anticipation of the films release in November, and ahead of the full length trailer which is scheduled to hit the net on Tuesday, September 13.

The teaser trailer shows a pregnant Bella (Kirsten Stewart) and an anxious Edward (Robert Pattinson). Aware of the dangers present in a vampire/human pregnancy, Edward warns his new wife, “It’s crushing you from the inside out.”

And if that doesn’t present enough of a worry, werewolves led by Sam Uley (Chaske Spencer) are in pursuit of Bella and her unborn child, fearing the threat the child signifies.

The new trailer comes just days after the release of two new teaser posters for ‘Breaking Dawn: Part 1’ – With one of the posters clearly showing Bella’s wedding ring.

‘Breaking Dawn: Part One’ will hit screens in the US and UK on November 18.

Update: The Full-Length Trailer Has Been Released.
