We all know smoking while pregnant is bad for babies, but a new study shows working while pregnant could be just as dangerous, Fox59 reported.

Researchers at the University of Essex in the United Kingdom claim to have found that working into the late stages of pregnancy is just as bad as smoking.

Dr. Maret Cline with St. Vincent's Hospital said she wouldn't worry too much about this information, just yet.

"All studies in the past have shown, in a safe working environment that's not too physically or emotionally stressful, women can work up until their due date without any complications."
