You may just be having an off cycle which sometimes happens, even if you have always been regular before.

You can wait and see what happens with your period next month and test at that time if need be, or see your doctor. However, they will likely do a urine test in the office, which you could just do at home. You could ask about a blood test and see if they would do that for you.
