constant spotting

I have always had problems with my cycle, but the past few years I just haven't had one at all unless I took Clomid. I took the meds twice and aside from the period right after I've had none. A couple months ago I had a random period, then nothing. Last month I had one that lasted around 3 days. This month though I spotted, lasted 2 days, gone for two days, then started a period for 5, stopped for 2, came back for 2, then gone, now back. Has anyone else ever had this problem? I'm trying to get to the gyno but can't get an appointment till September.
