Ahhh, the waiting game ni memang tension! Darah dan lendir tu biasanya tanda cervix tengah buka, tapi timing baby memang unpredictable, a few of my mum friends also experience bloody show for days before anything happens, especially second time around. At 38w5D you're almost there lah, tapi since your first was induced, this time badan ni memang boleh ambil lebih lama to go into labour naturally. Definitely check back with your doctor if the bleeding jadi lebih heavy or if contractions start, tapi kalau sekarang still manageable, just rest and monitor yourself, baby will come when ready!
