Sayang, please go see your doctor or go to hospital straightaway okay, ngilu bawah and sengal-sengal macam tu at 27 weeks kena check properly, jangan tunggu lagi. A few of us mums went through weird aches during pregnancy and it turned out okay, but some things memang kena professional check, better safe than sorry kan. Jangan risau, doktor akan tahu what's normal and what's not. Take care of yourself!
