My period is 32 days late. took many tests, last being yesterday and all is negative. could i still be pregnant?

Not if last sex >3wk: Home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, or medications. A correctly done urine 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 no sexual activity in the last 3 weeks, then the test should be accurate (meaning not pregnant).
