How did depression affect your pregnancy?

I'm not speaking of postpartum depression, but prediagnosed depression. If you had depression before getting pregnant what was your experience like? Did you still use medications while pregnant? Did your depression affect your pregnancy? How was after birth when postpartum depression is common? Was it hard to not be depressed, tired and uninterested with your baby at any stage of their life? My husband wants a family so much but I am afraid of not being a good mother because of depression and OCD. I know every experience is different but I would like to hear the good and from bad others.
