Please help ease my mind

I'm due for my period in 2 days I took a test a day ago and it came out negative but I took it midday after drinking a lot of fluids so it's probably not accurate. I've had abdominal cramping for 2 weeks now and I never have cramping 2 weeks prior to my period. Now that the time gets closer I'm more nervous and these cramps are beginning to make me even more nervous. Anybody else have this and end up pregnant?
