Saya pun pernah alami ni! Usually it's ligament pain (round ligament pain) sebab perut stretching, lagi-lagi kalau you're in your second or third trimester, memang sakit sebelah jer sometimes. Tapi sebab pregnancy complaints boleh jadi banyak benda, better to mention it to your doctor at your next checkup so they can make sure everything's okay, especially if it's getting worse or you're worried.
