Very unusual period, what is up?!

Okay my last period was 8-17 (I'm irregular and have long cycles) and it was due 9-27!. On 9-28 I started spotting!. Pinkish with cramps and fatigue and aches and the whole PMS thing!. Today (9-29) it is slightly heavier (I only need a very light pad or pantyliner)!. I'm still getting some PMS symptoms but not as bad!. Usually by this time its so heavy I gush when I stand up in the morning!. Physically I feel like I'm PMSing halfway!. My normal cycle is usually light the first day (not spotting light but still light) and at its heaviest on days 2 and 3 then tapering off until day 5 or 6!. I don't know if this matters but I also had breast tenderness from 9-8 to 9-16!.
For any other questions: I have not had sex in a little over two months (3 weeks before my last period)!. no, I'm not on any medications!. no, I don't want to be on birth control!. Its been almost 7 years since I started my first period!.Www@Answer-Health@Com
