u had grade 1 or minor dysplasia
in ur last pap's smear report. this can be a normal finding or may indicate inflammation, but not cancer.
so it is advisable for u to go throu the test every year for next 3 years, untill 3 reports are normal.
just postponing the test for 1 month will not give rise to much difference, but get it done as soon as u get time.
