Anytime you have unprotected intercourse, there is the risk of pregnancy. Yes, you could be pregnant. Wait another week. If your period still has not started, repeat the pregnancy test. If it continues to be negative, you may be skipping a period.
You may want to make an appointment with a gynecologist to discuss your menstrual history, and to discuss beginning a long term method of birth control.
