My cycle is normally 28 days and i was on day 34 when i began bleeding which contained clots was heavy but lighter than my regular cycle(5days) and lasted > 2 days. could i be pregnant?

It's possible if: U are having unprotected intercourse. Take a pregnancy test, that's the best way to answer that question. Consider the birth control pill if negative to regulate the cycle and prevent an unplanned pregnancy. If necessary u could go to a health unit.

OBGYN/ BC: Pregnancy is a possibility, but remember that periods between 21&35 days still normal. Recommend a pregnancy test, if negative just wait and see the next cycle.
