I am two weeks late on my period and I have taken two pregnancy tests and they both came out negative. I have had a raise in stress levels but not enough to cause that much of a difference. I am having a lot of symptoms of pregnancy but I am still confused if I should test again or just wait it out?

You could give it several more days and try another test, making sure that you follow the directions exactly, or wait until when you would expect your next period. Have you used any sort of birth control recently? Any change or start of medications? Stress can sometimes play a role, and there isn't a set amount that it has to be to cause a change... quite individual even if it hasn't happened before.

If still no period, try another test at that time or see your doctor. Sometimes periods can be off for a variety of reasons or no apparent reason at all. It may still show late or you may even skip a cycle altogether.

I would get a blood test. Maybe you are!
