Can you still be pregnant if your 12 days late and all pregnancy tests are negative?

False Pregnancy Test: It is possible to get a negative result from a home pregnancy test when you're actually pregnant. This is known as a false-negative — and it's much more likely to occur than is a false-positive. You might get a false-negative if you: miscounted days (repeat in 3 days), the test kit is defective or expired, didn't follow the correct instructions or if missed period due to other conditions.
