Sayang, I totally understand your worry, it's so normal to be anxious about baby bila ada situation macam ni. Tapi since your doctor dah assess dan okay the surgery, that means they've weighed the risks carefully, especially at 25 weeks. The best thing is to trust them and ask all your detailed questions directly, like exactly what they'll do to protect baby, what anaesthesia they're using, and what to watch for after. Go in with a list so you feel more confident, okay? A few of my mum friends pun had procedures during pregnancy and baby turned out fine, tapi setiap case berbeza, so your HKL doctor really is the one to discuss all your specific concerns with. You deserve to feel as reassured as possible before you go in. Sending you strength!
