Salam sis, honestly this sounds like something kena check with your doctor soonest, especially since you're still in pantang period, itching dalam faraj after delivery (terutama C-section) boleh be anything from normal healing irritation to infection, and kena kena ruled out sebab you're still healing. A few of my mum friends had similar gatal-gatal during recovery, tapi they got it checked just to be safe, better safe than sorry lah, especially when you're only 14 days postpartum. Try not to scratch kahkah (I know susah!), keep the area clean and dry, and just message your gynae or go to the clinic, they can properly assess whether it's just part of healing or something kena treat.
