Hai! At week 6, ligament stretching dan uterus yang sedang membesar memang boleh cause cramping mcm tu, tapi kalau rasa berdenyut-denyut sebelah je, better check dengan your doctor or midwife jus to be safe, okay? A few of my mum friends also had weird cramping sensations early on tapi the doctor confirmed semua okay, so don't worry lah but do get it checked out, biar tenang hati! Take care of yourself
