I'm sure part of the obsessing is the OCD, and this is a cruel vicious circle to be caught in.

Lorazepam is not recommended for use during the first trimester as other benzodiazepines have been found to cause problems for the developing fetus. However though it is to be prescribed with caution it is generally safe for use in the 2nd and 3rd tri's if taken under medical observation. It is recommended that you stop taking it before the birth as it can cause depressed breathing etc. at birth, but you are only to take it for a month, so that's not a concern.

Your doctors know you are pregnant, so yes, you will be safe to take this medicine and get some relief from the anxiety of OCD.
