bad cramps and creamy white discharge a week before period?

katie

I have been having awful cramps for a couple days and I dont have any explanation. I don't think I could be pregnant because I haven't had unprotected sex since.. august. But I didn't get a normal period last month it was just brown spotting. I also notice quite a bit of creamy milk white discharge. Is this a sign of pregnancy? Or is it too long after last unprotected sex. Thanks to whoever will help!!
