Sayang, tu boleh jadi banyak things, anemia, thyroid issue, atau just hormonal changes especially kalau pregnant atau postpartum. Tapi yang penting, jangan delay, go see your doctor or go to clinic ASAP , especially kalau panting and shortness of breath, okay? Nak tau apa yang happening tu kena check proper. A few of us mums dalam WhatsApp group pun pernah complain pasal tired and breathless jugak, tapi once dokter check, lega je because tahu apa problem dia. Take care of yourself first, ya!
