Light pink discharge a day before period?

Hello.

I am due for my period on 10/14/14. However, I have some light pink discharge with mild cramping going on that started around 8pm or so tonight. My breasts have been sore for about a week or so. I finished my second round of Clomid last month on 9/20. I went and Googled to see whether or not Clomid could bring on a early period and from what I read, it doesn't. Anyone else experiencing this or have experienced this and it turned out you were pregnant?
