Salam! Sayang, dentures dan cramping tu memang boleh jadi normal dalam early pregnancy, tapi sebab ni sensitive dan you're only 5 weeks, please call your doctor or go to the clinic as soon as you can, jangan delay . Especially kalau jantung palpitations pun ada, doctor perlu check you properly. A few of my mum friends rasa macam tu in early pregnancy tapi semua orang lain, so better safe than sorry lah!
