Perut mengeras tu memang boleh jadi normal dalam pregnancy, especially kalau ada Braxton Hicks contractions atau uterus tengah expand, tapi since you're only 14 weeks, better check dengan doctor je to be safe, sebab timing tu still early. Mum friends of mine pun pernah alami, but everyone's pregnancy lain-lain, so tak boleh compare, paling senang cek dengan midwife or OB you to make sure everything is okay. Jangan risau sangat dulu lah, tapi jangan delay check-up also!
