Late period... Negative pregnancy

Hello everyone! I'm sort of in freak out mode bc I have never in my life missed a period or really had irregular periods ever with or without birth control and I am over a week late with multiple negative pregnancy tests. I was on birth control for several years and I got married recently so I stopped. We have been trying for about 6 months and my cycles have all been regular up until this month... My period hasn't come. I don't know what's happening bc all the pregnancy tests I take say no baby but where is AF?!?! It's left me confused, frustrated and a bit worried! HELP!!!!!
