Im now a week late your opinion please?!

I had sex the weekend of thanksgiving that Saturday and Sunday! My period should have came December 3 but a no show. I've been cramping in my stomach and down low like my period is coming! I would say day 5 or 6 of being late the sides of boobs started hurting out of no where , last night they where painful to even lay on. My periods have been coming early and I have white discharge , I was sick with a little cold but nothing serious from my sinuses. Tomorrow will make 2 weeks since I've have sex. Should I gone ahead and test? Some people said wait
