Sakit dada masa pregnant memang biasa, especially dengan hormonal changes, tapi sebab ini boleh jadi banyak reasons, bisa dari breast tenderness, posisi tidur, atau sometimes anxiety. Saya suggest you check with your doctor or midwife to make sure it's nothing serious, sebab they can examine you properly dan give you peace of mind. In the meantime, try wearing a supportive bra, ensure you're comfortable when sleeping (maybe bolster untuk support), dan try to relax, stress pun boleh trigger rasa sakit. Bagaimanapun, don't worry sangat, most mums experience this, tapi best to get it checked just to be safe.
