Does Being On Zoloft And Copaxone Cause Difficulty In Pregnancy?

My daughter just recently came off of Klonipin and Geodon, is weaning off of Triliptel. She is on Zoloft and copaxone. She had steroid induced bipolar reaction 5 yrs ago and has remarkably improved. She wants to get pregnant but is being told different things by different providers. Some say yes, it's fine, others say she could have issues, baby could go through withdrawal. Your thoughts please.
