Taking luvox, buspirone, wellbutrin, and trazadone during pregnancy?

Hi! I'm two months pregnant with my first child at 26 years old. I don't want anything to happen to my baby, but I'm unsure what to do. I have been diagnosed with OCD, post-traumatic stress, and depression with psychosis. I'm scared that if I get off the medicine my symptoms will return. I want to continue school in august and I don't think I will be able to if I get off of the medicine. Can anyone please help me? Can taking all this medicine together be harmful for my baby?
