I'm pregnant and on anti-depressants, anyone else experience this?

Before I go on, I am going to ask my gyno when I see her next week, I'm just looking to see other peoples experience!!

I've just started Welbutrin (Bupropion) about a month and a half ago, and am possibly 3-4 weeks pregnant. I don't want to continue if its going to cause any harm how were others? Did you maybe switch during pregnancy to a safe on (if this one isn't?)
