Wa'alaikum assalam! Sayang, cramping tu normal masa pregnant, tapi since you're worried about labour signs, better check with your doctor or midwife first, they can confirm if it's Braxton Hicks or something else, especially kalau ni dekat due date you. A few of my mum friends experienced similar cramps tapi turned out just practice contractions je, so jangan stress dulu! Keep monitor lang kalau ada signs lain macam water breaking or bloody show, then terus go to hospital ya. Take care!
