It's no worse than a regular flu, and you have no greater chance of getting it than regular flu. Do you live in terror every year over the regular flu? No. So why would you over this one.
And the media is jumping on it, like they do any time there is going to be a NEW vaccine for something. Please don't be one of the sheep lining up to get this NEW, UNTESTED, INEFFECTIVE, vaccine. I find it so funny that people just want to get a shot for something... anything... out of fear of the unknown. How about fear of the vaccine? There is no research and flu vaccines are highly ineffective, anyway. Plus, the new vaccine WILL contain thimerisol (mercury) if you get one from a multi-dose vial. Scary stuff, that is.
Just eat right, take your prenatal vitamins, get 1000-1500 extra mg of Vitamin C, take fish oil... exercise... just keep your body really healthy. Eat tons of fruit and veg... just take care of yourself. And NURSE THAT BABY for as long as you can, so that she is protected with your immunity during the upcoming cold and flu season.
In short, the swine flu is not a threat to you any more than the regular flu. THOUSANDS of people die of the regular flu... of the common cold, even... every year. You don't worry about that, do you?
Don't fret. :)
