I've been hearing that some people are discouraging prenatal testing for halachic reasons but it seems pretty important to me.

Does anyone know if there's actually something halachicly wrong about doing these tests?

What kind of testing? Genetic diseases? Sex? Paternity? – Monica Cellio May 1 '12 at 18:44

See this answer. Those rabbis who prohibit aborting a fetus even if it has Downs, Tay-Sachs, or the like, strongly frown upon testing for such things if there's nothing you can do about it -- or you'll put yourself in a situation where it will take superhuman strength to follow halacha.
