Eh sayang, sadly heartburn ni boleh jadi persistent sampai delivery, especially dekat 3rd trimester sebab uterus pressing against stomach lagi teruk, a few of us dari mum group still kena sampai last month! The good news is ia tak selalu teruk sama macam second trimester, so there's hope it settles slightly, but best to chat dengan doctor pasal safe options macam antacids atau posture changes yang boleh help. Setiap pregnancy lain sikit, so yours might improve more, tapi jangan expect ia hilang completely sampai baby keluar, dear. Take care!
