Wellbutrin and heavy period

Has anyone who has taken Wellbutrin experienced heavier and/or more painful periods?

Normally I can go about 5-6 hours on my second and heaviest day but I couldn't even make it 3 and a half today. My last period was all messed up and I spotted for two weeks and then when I was supposed to get it, the spotting stopped...I talked to my doctor who said it could be from the Wellbutrin and to just ride it out. But my periods are getting heavier and more painful the more I'm on this. I'll be going to see my doctor today but I thought I'd ask and see if anyone else is experienced this?
