Have you had any symptoms of PMS? Like getting the normal cramps and such? I had a similar situation, even with similar dates, but it was that it was taking forever for my period to start, and I was worried that I was late. It finally started, but I was having my normal cramps. Don't worry, it won't help to worry. Plus, stress effects your cycle, too. I would take a pregnancy test, and that knowledge will put you in control. That's what I did and it said that I wasn't pregnant. Best to you.
