I wouldn't be concerned about this minimal exposure at that fetal age or any other stage of pregnancy. It is good to avoid meds when you can but a mother that can remain productive and healthy is also important. This is listed as a category c drug which just means they don't have enough data to say it's perfectly safe but existing data are not worrisome.
