Sayang, situation macam ni kena monitor closely, please jangan tunggu lagi, go back to hospital or call your doctor sekarang juga untuk update, especially since you're at 37 weeks with placenta previa. Tanda coklat berhenti is good news, tapi baby hardening tanpa sakit clear (even if kadang-kadang je) kena discuss dengan doctor sebab dia yang tengok bukaan 1cm tadi, maybe it's Braxton Hicks, maybe it's early labour, tapi dia je boleh confirm. A few of us mums pernah in similar situation and the doctors prefer to check properly rather than tunggu at home Jangan takut, just go get peace of mind, it's better safe especially with PP Type 1!
