although home pregnancy tests are relatively accurate the blood test done at your doctor's 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.
i took 2 pregnancies tests at home that were positive. i went to the dr and blood test said not pregnant. i'm confused. my period was 2 days late but i did get it for 3 days. could i still be pregnant?
