Sayang, at 37 weeks with that sound and growing pain, please go to the hospital or call your delivery ward sekarang juga, don't wait to see if it settles, better safe than sorry! Even though baby is moving fine and nothing came out, the midwives need to check you properly in person, could be anything from baby's position shifting to something they need to monitor, and at this stage it's not worth guessing at home. Your KK staff know you already, so go back there or head straight to the nearest hospital if it's faster. Jangan risau, you're almost there!
