Spotting durring predicted ovulation window?

Okay, and has anyone here had any spotting? I had awful cramping the 3rd, and the 4th. I may as well add today as well, because I just got a cramp. It is mild though compared to the 3rd, and 4th. The spotting started on the 5th, and the 6th. It is nonexistent at points, but starts up at random times. I googled, and saw that it was rare to bleed before ovulation. Granted, I am not sure if I’ll ovulate this month. My boobs are a little tender, but not bad. I’ve 2 more days to ovulate. So far, I’ve not had a surge at all.
