Mama, please check with your OB first bago ka mag-take ng kahit anong gamot, lalo na kung pregnant ka pa lang. Mas safe na marinig mo directly from your doctor kung okay lang yan sa baby mo, kasi every pregnancy is different. Yung kati ng lalamunan kaya rin ng simple salt gargle or warm water, at maraming momshies na nagta-try nito. But your doc can suggest what's best for you talaga. Take care, okay?
