Aih, sabar ya ibu, ramai je yang kena macam ni masa pregnant, you're not alone! A few of my mum friends went through this and they all swear by keeping things really moist down there (pakai wet wipes yang lembut or bidet kalau ada), plus jangan force when going to the toilet, biar natural je, minum plenty of water and makan banyak fiber macam sayur, oats, buah-buahan. But since you're worried and it's bugging you, better check dengan doktor sebab sometimes they boleh recommend creams or suppositories yang safe untuk pregnant mums, don't suffer in silence, okay!
