Hi, i'm currently 3 days late and last night before bed i started to get some light pink bleeding/discharge still possible to be pregnant?

Yes, if . . .: If you engage in unprotected sex, then being late for your menses/period is sign of pregnancy. Best way to confirm is to take home pregnancy test. These are available at most drug stores w/o prescription. Very inexpensive & very accurate. Regardless of result, go see your Family Doc, GYN or Planned Parenthood to discuss birth control or prenatal care, as appropriate.
