Oh, sabar ya mummy, this is actually quite common during pregnancy, the skin around that area becomes much more sensitive due to hormonal changes, extra moisture, and the friction from your growing belly and thighs rubbing together more than usual. From what I've generally heard, keeping the area clean and dry as much as possible really helps, and wearing loose, breathable cotton underwear makes a big difference in reducing that irritation. Some mums I know swear by applying a gentle barrier cream or petroleum jelly on the affected area to protect the skin from further friction throughout the day. Do be cautious with any medicated cream though, as not everything is safe to use during pregnancy, so it would truly be best to check with your own doctor or O&G specialist to get the right advice for your specific situation. Take care, mummy, you're doing wonderfully!
