I suspect that you're referring to the short-lived Strange World.
Strange World was a short-lived sci-fi series in the tradition of The
X-Files. ABC cancelled it after airing three episodes due to poor
ratings. The remaining ten episodes were picked up and aired by the
SciFi Channel.
Strange World revolves around Captain Paul Turner. While serving in
the Gulf War he was exposed to chemical weapons and developed aplastic
anemia. Also a doctor, Turner works for USAMRIID (United States Army
Medical Research Institute of Infectious Diseases) where he
investigates the unethical uses of science, medicine, and related
technologies. He is approached by a mysterious Asian woman who gives
him a temporary cure for his symptoms. She works for a shadow
organization whose goals run counter to USAMRIID.
In Lullaby, Cass is a young pregnant woman. She fears her doctor is
trying to kill her unborn child. As Turner investigates, he learns
that Cass is a surrogate mother and there may be something to her
story. Many of her doctor's patients mysteriously miscarry at 6
months. There's a medical experiment being performed on Cass and the
others. Callum plays Vince, Cass's boyfriend, who tries very hard to
do what he believes is right.
