Any ladies help or experience similar....

Been experiencing cramps on and off for the last week and my boobs and chest have become really veiny along with my stomach and pelvic area.

Due period in about 5 days but could this be an early pregnancy sign?

Is it too early to test or should I wait and see if my period arrives on time?
