Aiyah, batuk teruk memang sakit, but better to check with your doctor or midwife first lah, some lozenges are okay during pregnancy tapi some ingredients better avoid, so don't risk it! A few of us preggers friends just gargle with salt water or minum warm honey and lemon instead, and it does help soothe the throat without the worry. Your doctor can also recommend throat lozenges that are safe for 20 weeks, so just give them a quick call or pop by, they will know your situation best! Get well soon, mama!
