Aiyoh sakit tekak when pregnant memang annoying! A few of us tried gargling with salt water (warm, not hot!) and it really helps, plus drinking lots of warm liquids like honey lemon tea, memang soothing and safe for baby. But since you're already 24 weeks, best to check with your OB or doctor just to make sure, especially if it's getting worse or you have fever, because sometimes pregnancy lowers our immune system a bit and they might want to monitor it.
