So worried

I know I should probably make a doctors appointment... here's the deal... I started AF on 6/13... I have a normal cycle 28 days with usually a 4 day period light spotting on day 5 sometimes in the morning.... but it is almost at the end of day 6 and I'm still spotting!!! Never in my time since I was 11 has this happened... I had an abnormal pap in January but it said no need for further testing come back in a year I thought maybe the abnormal was because I had sex the night before... but now I'm beginning to wonder...
