Hi, i recently got married and moved to united states from india. i had my period on august 3rd 2014. i am due 13 days now. negative pregnancy tes?

Menses: From what I gather you should have had your period around the 4th of September. If you are not pregnant, I still would do another home pregnancy test in a few days or get a blood test at the doctor, your periods could be irregular from the stress of your new marriage and or your moving to a new country. If you don't become regular again then I would visit a GYN after 1-2 more months.
