Wah, 6 anak subhanallah! C-section kali 4 memang ada risk lebih sikit especially with scar tissue, so definitely kena discuss thoroughly dengan doctor pasal timing and safety, a few of my mum friends yang BTL after multiple C-sections semua kena plan detail-detail dengan their OB pasal wound healing dan complications risk. BTL itself straightforward ja, most mums recover well, tapi the combination of 4th C-section + BTL is something your doctor perlu assess specifically untuk your situation. Doa2 everything goes smoothly!
