 [ Symptoms ] i took 2 pregnancies tests at home that were positive i went to the dr and blood test said not pregnant i am confused my period was 2 days late but i did get it for 3 days could i still be pregnant [ Disease ] although home pregnancy tests are relatively accurate the blood test done at your doctor is office is more sensitive it is unlikely that you are or were pregnant especially since you started your period even if you had a very early miscarriage the blood test would most likely still be positive at this point there is no way to know why the home pregnancy tests were positive if you had your period for 3 days you are not pregnant
