Itchy skin?

I'm only 4 weeks and 2 days but I've noticed I keep getting itchy spots on my skin that are out of the ordinary. Especially right where my public hair starts, right on that line is soooo itchy out of nowhere. It's not itchy any lower than that. Legs itching, tops of feet, back, arms. It's not horrible but just something I noticed. I think I'm way to early to have high Bile Acids (sister in law had this and has rashes from head to toe and itches her skin raw) so anyone experiencing this or is it just dry skin?
