Aih, gatal-gatal masa pregnant tu memang biasa, especially 12 weeks ni hormones tengah lagi naik! A few of my mum friends complained pasal gatal ketiak dan between thighs jugak, usually it's dari stretching skin, humidity, or friction area jadi lembab. Try keep those areas dry, wear loose cotton clothes, and if it's really bothering you, just mention to your doctor at your next checkup to make sure it's nothing else, better safe than sorry first pregnancy kan. Mana tahu doc suggest something ringan je untuk settle the itch. All the best, mummy!
