Ay mama, 34 days delay is definitely worth a pregnancy test na, lalo na kung irregular periods ka talaga kaya mahirap ma-predict! Since nangyari na sa'yo ito before at hindi mo namalayan until 4 months, better get a test now para sure, could be a false alarm or you might actually be expecting na. A few of us moms din ang irregular, kaya I know how confusing it is, pero once you test, at least you'll know what to do next, diba?
