Mama, please check with your OB right away, hindi dapat ikompromiso ang ganitong symptoms sa ganitong stage ng pregnancy! Alam ko scary lalo na kung iba ito sa first pregnancy mo, pero only your doctor can tell kung normal heaviness lang or something that needs attention. Maraming moms sa amin ang nag-experience ng pag-bigat at back pain towards the end, pero kailangan talaga ng medical check para ma-rule out ang preterm labor at iba pang concerns. Tawagan mo na ang clinic mo or puntahan mo sila ngayong week, better safe than sorry, diba? Praying everything's okay with you and baby.
