Period is 7 days late with negative blood test, could i be pregnant? i also have early pregnancy symptoms

Not likely: If you're late for your period. But your pregnancy test is negative then you're likely not pregnant. If you're worried repeat the test in 5 to 7 days. There could be other reasons that your period is delayed. If you don't want to be pregnant make sure you're using a reliable form of birth control. Early pregnancy symptoms are similar to premenstrual symptoms.
