Slight cramps, bloating and gas, should I be worried?

I had sex with a condom and it never broke, tore or anything like that. He never ended up cuming but when he pulled out the condom began to come off . I'm due for my period in 3 days and for the past 2 days I've had slight cramps, bloating and gas. The cramps feel normal to as if I was about to begin my period soon, but I'm still worried.. I have not gained any weight or had any other signs of "early pregnancy." Should I be worried or not?


Please help!
