Uy, mama, please go to your doctor or the hospital right away, lalo na may asthma ka pa, kailangan talagang tingnan kung ano talaga ang nangyayari. Hindi ko dapat sabihin kung normal yan or not kasi medical siya, pero parang importante na ma-check properly, lalo na yung tiyan mo na naninigas. One of my mum friends had similar breathing issues at napakaimportante na nabigyan siya ng proper check-up, don't risk it, ha. Punta ka na ngayon kung kaya mo; kung pakiramdam mo sobrang hirap or suddenly worse, go to emergency na. Take care of yourself, sis!
