period is late

Okay so my period is almost 3 months late. I've had a couple of episodes where I thought I was gonna start where I was spotting but didn't last longer than a day. I've taken multiple pregnancy test a BFN. I am currently taking Paxil 20mg daily for anxiety and depression. Anyone know why this is happening and I don't have insurance so I can't go to the doctor. Does anyone have any advice?
