from my own understanding po, pwede po as long as low consume lang kasi may caffeine ang Tea. like isang baso lang. kung kaya mo, try mo uminom hot/warm water. or ginger with kalamansi drink po. and kung may plema po, Try to force yourself na ilabas yung plema. noong 16 weeks preggy ako, Inuubo talaga ako like dry cough na may konting plema. nagpacheck up ako kay doc, the doc prescribed me Nebule atsaka antibiotic tablets.. and nawala po ang ubo ko.
