Anyone cramp and end up pregnant?

I'm on cd 24 today. On cd 21 I had brown spotting in my cm. Nothing since then. I have had some cramping today. I'm not due to start my period for 6 more days most likely (my cycles are 21 to 30 days. Usually 30). The fact that I spotted then had nothing makes me hopeful but the fact that I was cramping discourages me. Anyone have a similar experience and end up being pregnant? On a normal cycle I spot the day before I start and more than what I recently spotted.
