Aww sayang, I can really understand how scary this must be, especially after being warded twice. Cervical erosion memang common dalam pregnancy sebab hormone changes dan increased blood flow, tapi memang boleh jadi stressful. From what I hear, most mums in similar situations found that bedrest does help reduce the bleeding, activity memang trigger it more, so your body is telling you something. Posisi tidur probably does play a role (some mums swear by sleeping on their left side to reduce pressure), and the spotting/bleeding usually continues until baby is born or the cervix heals postpartum, though some mums reported it eased around mid-pregnancy. Honestly, since your baby is growing beautifully Alhamdulillah, the main thing is just being very gentle with yourself, light activities only, and if the bleeding becomes heavy or you get cramping, that's when to rush back to your doctor. Your specialist knows your case best, so do double-check with them again about any warning signs to watch for. Doa yang terbaik untuk you and baby, sabar ya.
