Hi mama! I know na nakakaingat yan, pero please see your doctor soon, kahit hindi urgent, better to check para sure ka na. Ang second trimester ay may maraming normal changes, pero gusto mo talaga na ma-assess ng medical professional para ma-rule out ang ibang possibilities, ha? One of my mum friends kasi had something similar at naging ligaments lang stretching, pero importante talaga ang check-up para peace of mind mo. Keep safe, mama!
