Back pain tu memang boleh jadi normal dalam pregnancy, even early on, tapi dengan sendawa yang tak berhenti at night sampai boleh jaga tidur, better you check with your doctor to rule out anything else lah, a few of us had similar issues and turned out fine, but some needed a bit of attention from the doc, so tak rugi pergi check. Morning sickness tu memang tak semua orang dapat, so jangan worry about that, tapi the combination of things yang you're experiencing sekarang kinda warrants a quick checkup je to be safe.
