Sayang, chest pain during pregnancy kena check dengan doctor terus, especially kalau susah bernafas. Jangan tunggu-tunggu, go to your nearest clinic or hospital sekarang juga okay? Better safe than sorry when you're pregnant. It could be something simple macam ligament stretching or rib pain yang normal dalam pregnancy, tapi doctor je yang boleh confirm and make sure baby okay. Jangan worry too much, most of the time it's nothing serious, but you really need to see someone today.
