Your best bet is to get a blood test from the doctor.

I agree with the previous post, you should have your doctor do a blood test. I have been told that it is normal for a woman to miss at least one period and it usually happens when you are ttc. I was 7 days late once and my sister in law missed 3 periods in a row.
