If it's just regular itching try Jamaican castor oil. Its an orange cream that can be picked up from most hair stores,well at least the ones here in Florida. It's fairly inexpensive. Works miracles though
I second the cholestasis. I had it and that's how it starts then it spreads and you start scratching your skin off. If you notice intense itching anywhere else deffinatly ask about it. If you do have it they give you a pill to surpass it till birth.
I think you're fairly far along right? Ask your doctor to have blood work done for cholestasis just in case. Usually its hands and or feet itching but can be elsewhere
How far along are you? Do you have a slight rash on your stretch marks if you have any? I had pupps when I got closer to my due date.
