### Human:\nhow common is a false positive pregnancy test. my expected period was suppose to be sept 25 it never came so i took a test fives days later it came up positive could i really be pregnant?\n\n### Assistant: hi if you have been having unprotected sex? what else would you expect a pregnancy test to show if this was a home test and you don't trust it just pop of to your doctor and get one there. don't worry i'll wait here for you and your result. good luck
