Hai sayang, cramping tu memang normal dalam early pregnancy, hormones dan uterus yang tengah adjust boleh terasa mcm period pain! But since you're only 5 weeks, memang masa yang sensitive, so jangan ambil risk, better text your gynae or clinic just to make sure everything okay, especially if the pain tu heavy atau ada spotting. A few of my mum friends experienced the same thing and doktor mereka semua say it's normal, tapi they still checked in just for peace of mind, and that's the smart move at this stage. Take care!
