Missed period

Paige

I was supposed to start my period sunday. I’m currently 4 days late with no spotting. Some mild cramps here and there but that’s it. I’ve taken a couple test and they are all negative. Rewind to last month... I was put in Wellbutrin for my depression. My question is has anyone missed a period bc of antidepressant before? I know it can happen but I didn’t think it would the first month of taking them
