Sayang, itching during pantang is quite common actually, a few of my mum friends experienced it too! But sebab it's day 20 pa, better you check with your doctor or midwife first, ok? Bisa jadi normal or bisa ada something else je, so jangan risau but do get it checked cepat-cepat. Mana tahu ada heat rash or lotion reaction ka, doc akan tahu better. Jaga yourself, ya!
