Kejang bawah perut at 29 weeks biasanya normal, sayang, tu Braxton Hicks contractions atau ligament stretching sebab baby growing, tapi kalau sakit sangat atau disertai bleeding, kena check dengan doctor cepat-cepat ye. Few of my mum friends had the same thing around third trimester and doc assured them semua okay, just part of the journey lah, tapi jangan ambik risk, better safe than sorry when pregnant kan.
