Difficult issue: Any secretions from an excited male penis can carry enough sperm to impregnate you, so the pull out method is not a dependable form of contraception. Several negative tests suggest your delay is not pregnancy, but it might be if the tests were of poor quality.Occasionally women can fail to ovulate, and have a natural delay. Give it some more time and discuss it with your doc if > 30 days.
