Sayang, tu Braxton Hicks contractions la, perfectly normal at 36 weeks, especially first time mums! A few of us experienced the same thing, perut keras terus especially bila gerak or buat aktiviti, super annoying kan. But if it's happening every day macam nih and you're worried or ada spotting/bleeding or contractions yang regular and painful, better check with your doctor just to be safe, GP boleh confirm everything is fine and give you peace of mind, sebab first pregnancy memang banyak questions. Jangan stress ye, most of us went through this and lahir dengan lancar je
