My cycle is usually 28-32 days. I didn't have a period in September but I started October 3rd. My period usually lasts 5-6 days and was normal as I got off October 8th. I started spotting around the 24th of October, very light spotting a light pinkish color. I spotted very off and on that entire next week. Here we are on November 7th and I am still spotting, but more on a regular basis than just here and there. At this moment, it is a brownish color, too light to really wear a pad. I have no other symptoms no cramping or anything. What could be the cause of this.

I am 25 years old and am sexually active. I am not on any form of birth control and have had a history of ovarian cysts, but I can usually tell when I have a cyst. It usually causes cramps to one side of my stomach.
