Sayang, shortness of breath and chest pain during pregnancy tu boleh ada banyak sebab, some normal, some perlu check dengan doctor. Since you're experiencing this, please see your doctor or go to the clinic/hospital as soon as possible to get checked out properly, okay? Don't wait or try to manage it at home alone. A few of us mummy friends have had pregnancy-related breathlessness and chest discomfort, but each person is different, what matters is getting proper medical assessment so they can rule out anything serious and give you peace of mind. Better safe than sorry when it comes to you and baby. Take care!
