thanks for your query.
There is one really easy way to know if you are pregnant.
As you are already a week late, please take a home urine pregnancy
test tomorrow morning with the first voided urine sample.
If it is negative, there could be other reasons like stress, anxiety, weight gain or weight loss
, emotional trauma, frequent travelling, thyroid disorder
, polycystic ovaries
or uterine pathologies.
IF the test is positive, you would need to consult a gynecologist.
Even if the test is negative, please see a doctor if you do not have your periods within a few days.
