Eh sayang, baby keras-keras tu memang normal lah at 37 weeks, itu practice contractions (Braxton Hicks), bukan tanda nak bersalin lagi. But please call your doctor or go to the clinic to confirm, especially if you're worried, better to check than sit at home wondering, kan? A few of us mums went through the same thing and the doc put our minds at ease. If you're also bleeding, leaking fluid, or the hardness doesn't go soft after a while, then go to the hospital straightaway lah. Take care of yourself!
