Assalamu'alaikum sayang! Haih, ni serious situation betul, placenta acreta kena medical care yang proper, so memang kena dengar apa kata your specialist je, dia yang tahu condition mu paling detail. I know you're worried, and it's normal, surgery situation macam ni memang scary. The best thing is, you've got a specialist who's planning properly for you, so trust the process and ask them all your questions about what to expect on the day itself, recovery, dan semua. A few of us mums yang ada experience dengan surgery under general anaesthesia cakap yang important is to follow the pre-op instructions exactly (fasting, meds, etc) and have good support at home after. Wish you all the best for 18/12, you're gonna get through this!
