Hai mama, rasa lenguh macam tu memang boleh jadi normal di early pregnancy, especially sebab hormone relaxin tengah relax ligaments korang! Tapi honestly, 5 weeks tu still very early stage, so better check dengan doktor ye just to confirm everything okay, especially kalau the sensation tu persistent or getting worse. Dekat my circle of mum friends, few of us juga experience cramping and heaviness at the beginning, then hilang je; so don't worry sangat lah. Doktor akan check properly and beri peace of mind korang, which is really important masa awal pregnancy ni.
