Wellbutrin while pregnant

Does anyone take this while pregnant? I have always taking Zoloft and my OB switched me to Wellbrutrin. She said it's safer. Well the nurse actually switched meds bc the dr wasn't there. I told my parent and my dad is all worried about me. He was on it and it gave him really bad thoughts about suicide and other things that were not good like thoughts of killing people. He had horrible nightmares on it. Now I'm worried about being in this. I don't want to take it. I took Zoloft with my first kids and all was ok. My family is all worried about me so I'm not going to take it until I call and talk with the Dr. tomorrow.
