Ohhh cramping at 36 weeks tu normal sih, banyak yang rasa macam tu towards the end, bisa Braxton Hicks or just your body preparing lah! But since you're getting sakit-sakit, better check with your doc or midwife to make sure everything OK je, especially kalau the cramps are frequent or berpadu dengan other symptoms. A few of my mum friends had the same worry and doc reassured them it was just practice contractions, tapi better safe than sorry kan when you're this far along!
