Please stop spreading your anti-vax misinformation. A pregnant woman who gets the flu vaccine not only protects herself, but her baby, since the antibodies her body produces in response to the vaccine cross the placenta and are contained in breast milk.
As for "heavy metals"--I am not sure what you are even talking about. If that is a reference to the sodium azide or thiomersal used in some vaccines, the dose of mercury is extremely small, much lower than any established harmful threshold. A pregnant woman consumes much more mercury in a tuna sandwich than she would ever receive in a flu shot. Furthermore, the preservatives are not used in single-dose vaccine formulations, so it isn't a given that the vaccine even contains them.
You are crazy. To think that a flu VACCINE protects a mother and her baby best. Remember the Hippocratic Oath. First, do no harm.
If the pregnant woman has therapeutic levels of vitamins (and minerals) in her, and if she is unstressed and able to get enough sleep, she will not get a bad case of the flu even if exposed. That would meet the criteria of first, doing no harm.
Its insane to buy into giving a pregnant woman a shot into her muscle (bloodstream) filled with immune adjuvants, and all the other vaccine ingredients, believing it is somehow protective, while at the same time forbidding her an Advil or a drink of wine. Its not biologically logical.
The idea of vaccines is genius. The formulation is PRIMITIVE SCIENCE. The dosing, the recommendations, are outmoded and dangerous to some. And no one is able to know to whom a vaccine is dangerous just yet. Its quite the risk.
