Sayang, jangan tunggu, pergi A&E sekarang atau call ambulans, okay? Breathlessness and chest discomfort ni bukan typical end-of-pregnancy things yang boleh tunggu. Better safe than sorry, especially dengan GDM history. Doctor kena check you immediately to rule out anything serious. Once you're cleared, rest assured banyak ibu-ibu rasa shortness of breath towards the end, but the combination you're describing needs proper assessment, not online guessing. Go now, ya?
