Even if this drug is category "D", there is still the benefit outweighing the risks to consider.

Ativan and Pregnancy Category D
The U. S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category D is given to medicines that have shown clear evidence of risk to the fetus in studies. Pregnancy Category D is a stronger warning than a pregnancy Category C classification. A pregnancy Category D medicine may still be given to a pregnant woman if the healthcare provider believes that the benefits to the woman outweigh the possible risks to the unborn child.
Ativan was given a pregnancy Category D rating because of problems in animal studies. These studies suggested that Ativan may increase the risk of miscarriages and various birth defects.
Ativan is a pregnancy category D and should absolutely not be taken in the first trimester due to Large increases in birth defects. You should talk to your dr about taking a safer medication.
I think that is probably something you should talk to your psychiatrist and your OB about. I would not go off of medication for anxiety cold turkey.
