My cycle was 5 days early last month and is 4 days late this month...it always starts like clock works every month the same time. could i be pregnant?

Irregular Periods: well the fact that you are irregular is not usually associated with pregnancy. But it is always ok to check a pregnancy test to make sure you are not having some bleeding in early pregnancy that was mistaken for a period. It is not unusual to be a few days early or late due to changes in life experience going on around you i.e. stress.
