Depression confusion

Im currently taking zoloft 200 mg a day. My obgyn said it was safe for me to stay on while we try to concieve and during a pregnancy. I met with my new psychiatrist today and she goes on to tell me i have to stop the zoloft immediately, that it can cause a miscarriage or cleft lip or palettes. Im confused and concerned because my depression is under control but im scared of going off the meds but i havent found anything to support her claims of it causing birth defects.
