Aiyooo, tekak perit masa nak beranak memang biasa lah, mungkin dari stress atau tension, tapi sebab you dah so close to your date, better you beritahu doctor atau midwife you esok tu, they can check if it's just normal or ada something else, kan better safe than sorry. A few of us try gargle dengan warm salt water or honey, tapi honestly given your timing, just let the medical team know ok, they'll advise you properly! Take care and all the best for your C-section tomorrow!
