2 1/2 month late period

So my period was around 2 1/2 months ago. I'm not sexual active so I'm not pregnant. And I started my period 2 years ago. My periods are always a month or two late. I had cloudy discharge a day or two ago and then it stopped. I don't get pms and I can't go to the doctor, because I currently don't have health insurance. Any advice?
