I am had a irregular period for almost 3 months.. and now I already have a period but the problem is its almost 2 weeks and its on a and off meaning its not daily and until now I still have a period.. what does it mean?

It can mean many different things, from an unusual month of hormone fluctuations to something more serious over time, and there is no way to find out online. If bleeding isn't profuse and you don't have pain, just wait to see if there is change.
