Suggest Remedy For Itching In Vagina

About 14 months ago, I gave birth to my second child. A few months after that, I started to notice a severe itch around my vagina. The itch can sometimes extend to my clitoral area. It mainly happens at night or when I am on my period which seems to be heavier after giving birth also. I have tried salt bath 3 times a week and changing laundry detergent. Nothing helps. Is there something safe to take while I am breastfeeding?
