Brown spotting on Clomid?

Lauren

This is my first cycle on Clomid. I ovulated on CD 15 and had cramping, headaches, and nausea after which I was told were side effects of Clomid. My cycles are usually 26 days, and yesterday (cd 27) I got some brown spotting. I had taken a test in the morning and it was negative. I expected my period today, but it's all brown! And not nearly as heavy as af. Anyone have anything similar on Clomid? I've heard it can do some wacky stuff!
