Am I PREGNANT OR NOT?

Cera

ok so my period is very regular an this month it's just off. I was supposed to get it on the 6th an it was going to end today. And it hasn't come yet. I haven't taken a test yet but I haven't had any bad cramps like I would if I where about to get my period. should I wait to take a test to see if it comes? what do I do please help.
