Ay, mama, back pain in early pregnancy is common, pero since masakit siya talaga, better check with your OB para sigurado lang, wala kang risk or anything na dapat i-address early. A few of us pregnant moms naman, nag-share na nag-start din kami with aches around that time, pero kailangan talaga ma-monitor ng doctor mo. He/she can give you safe ways to manage it based sa severity. Don't hesitate to call your clinic, yan ang dali-dali lang, but peace of mind is important, lalo na sa early weeks! Praying for a smooth pregnancy for you, mamsh.
