I had a two day period very light bleeding. took a pregnancy test and it was negative could i still be pregnant.

Monitor cycles: If you have been having regular monthly cycles, the chance of pregnancy is quite low. Keep a menstrual diary and track your cycles. Light bleeding itself, is not a sign of pregnancy. If you have missed 1 month or more wait 2 weeks and repeat the exam- otherwise this is normal spotting.

Possibly - can: re-test in a week. The main reason for light periods is a change in hormone levels. Causes for what seems to be a light period can include: implantation bleeding in early pregnancy, thyroid problems, eating disorders, excessive exercise, initial periods for a girl, use of an intrauterine device, oral contraceptives & perimenopause.
