Can you name this movie?

Watched it a while back on demand with a blockbuster app on dish. Anyways, it's based on a Guy, his wife and her younger sister. The couple goes on a vacation to a wild life resort type thing with ahuge swamp. So the group takes a tour on the swamp and the boat gets flipped over leading to the group and tourist in the water. The tourist gets killed by an aligator and leaves the group stranded alone with no safety. They somehow find a way up in a tree to somewhat safety. From there on out, it becomes a survival mission with the group trying to avoid the gator, but also get in the water to retrieve the boat and get it running again. Being the only male left, he goes in the water to get the food and help the others survive. He finally gains thr confidence to get in the water to try and retrieve the boat, but ends up getting under the boat, and killed by the gator. Well it just so happens that the Wife is pregnant, and only has her sister to lean on. She still gets inthe water and gets bitten by the gator, but manages to survive and kill the gator in the process.
