Can u still be pregnant even tho test come back negative??

Pregnant ?: Home pregnancy tests may be "negative" if used at the time one's period is "due". Wait a week and if no period occurs, test again. If still in doubt, get a serum HCG test which is accurate even with low amounts of pregnancy hormone.

Sure, but unlikely: Home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, vaginal spotting, or medications. A test gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened) or 1 week after missing a period. If done sooner, a negative result may be due to testing too early such as less than 2 weeks after conception.
