Im 11 days late with tons of pregnancy symptoms but the test i took was negative. ive never been this late for a period ever could i be pregnant?

Try a different test: Why don't you try a different brand of test, such as ClearBlue? Some people are more accurate with one test than another. You can always check a blood pregnancy test with your doctor. In the meantime, avoid tobacco, alcohol, and other substances bad for your fetus, just in case. Some ovarian cysts can cause the above-mentioned symptoms without pregnancy.
