Wa'alaikumassalam! Sayang, perspiration banyak during pregnancy memang normal, especially dekat third trimester, hormones and body temperature naik. But kalau suddenly rasa extreme sweating with other symptoms macam shortness of breath, chest pain, atau dizziness, jangan delay, call your doctor or go to hospital straightaway ok, better safe than sorry! A few of us pregnant mums experienced the same thing, and most cases it's just hormonal, but you know lah, first baby everything feels scary so best get checked. Drink plenty of water and wear breathable clothes. Take care, mama!
