Aah normal lah tu, Braxton Hicks contractions tu, perut mengeras tapi tak sakit, and baby still moving is a good sign! A few of us mums experienced the same around 34 weeks, especially kalau activity level tinggi or dehydrated. Just try to relax, drink more water, and change position often lah, tapi if the tightening comes with pain, bleeding, or ada spotting, better check with your doctor just to be safe eh.
