4-5 days late, brown spotting, cramping

Annie

I know Angie posted something about this and I'm trying to determine what's going on.

I am Days from being 37 years old, I'm on cycle day 27 on a usual 23-24 day cycle and no real period. I was on 100 mg Clomid for this cycle, and for the first time.

A week ago, I had massive breast tenderness, cramps, and a yellow/creamy discharge. My period didn't come and pregnancy tests have been negative, including one yesterday.

As of this afternoon, I felt a sharp cramping in the left side of my pelvis and then noticed brown spotting. Barely anything when I went to wipe, except light pink/red. Later, again, all dark brown. Thoughts?
