There are heaps and loads of medications that are safe for pregnancies. Your caseworker is a caseworker not a Pdoc and an OB .. Your caseworkers opinion does not matter at all not one bit in this situation ( yours sounds idiotic)

As others have said you need to make changes in your medications and wait to see how your able to function and then consider a pregnancy. You wound want the best for your child and avoid anything that could cause harm or defects, So take the time to make well thought out decisions based on facts.

Good luck
