How soon do you have cramps?

My period isn't supposed to start for 10 days!
I'm having terrible cramping today :(
Normally they don't start for 2-5 days before!
I am sexually active and on birth control. However we don't use condoms. No bleeding, but have been having more than normal CM and it's been very creamy.
Anybody else have these symptoms before AF? Or even before BFP?
Truly don't think I'm pregnant but anything is possible I suppose!
