Pregnant & Antidepressants

I stopped my birth control this month because my boyfriend and I want to conceive. I started birth control again after a week because someone told me it would be hard to get off antidepressants so abruptly when finding out I was pregnant. However, it may be too late because I had sex during my fertile window. Has anyone come off antidepressants because of pregnancy? Did you taper or just stop them?
