vaginapagina | Antidepressants causing period changes?

I started generic Wellbutrin (bupropion) and generic Klonopin (clonazepam). I started bleeding 4 days before my period was scheduled. It was moderate bleeding. Now my regular period has started, I guess. So I'm probably going to end up bleeding 10 days instead of my usual 5 or 6. I can deal with some initial side effects like this, but not if this is going to happen every month.

Has anyone else had abornmal bleeding and/or spotting and a change in their menstrual cycle since starting antidepressant and/or antianxiety medication? Did the spotting/abnormal bleeding stop, and did your cycle go back to normal as time went on? Thanks in advance!
