Contraction signs? Tanda tanda contraction?

Hi semua. I’m at 32 weeks this week, and just wondering rasa sebenar contraction tu macam mana ya? I’ve read other posts saying that it feels like period cramp/ senggugut? Tapi I tak pernah kena senggugut sebelum ni. So tak pernah tahu. Also orang kata perut mengeras? I feel perut mengeras but I’m only assuming baby pusing pusing in tummy. Can you guys help to elaborate more rasa contraction ya? Thank you so much.
