I am sorry you are having all these problems. I would like to suggest that you make an appointment to visit with your physician bringing a list of all your sx as well as how you have been trying different ways of dosing to decrease side effects from med. You need to sort out what is a side effect and what is anxiety related.
Due to your pregnancy it is important for your physician to be involved.
I wish you the best in sorting this out .
