I am 37 weeks, and i just notice couple days ago some rashes like eczema patches on the inside of my thighs close to the lips, and it itches sometimes but not a lot. Ive never had them before im guessing is due to pregnancy, im getting checked every week and all my tests come out normal. So im gona say we have nothing to worry about.........i hope so.
It usually happens to me if my underwear/ pants are too tight or if the material is not breathable. Try buying new undies that fits right and is made of cotton. Keep the area down there clean and dry if you can because moisture attracts nasty stuff that causes irritation. Most importantly, get yourself checked to make sure that everything is okay. Hope this helps. :)
