Period timings vary from person to person and for many, they appear a day or two late, at times even a week or so late and that's normal too. Menstrual cycle length can vary from 28 days to 35 days and still be normal.
It's probably too early to think a period delayed by 2 days is due to pregnancy. Having said that, it's always a good idea to test with a home pregnancy test kit to rule out a possible pregnancy. Please talk to your parents if it does indeed turn out positive. All the best.
