Hello, I'm 15weeks pregnant and have been experiencing an excessive amount of hair loss. With my first child I had luscious hair and some hair loss after his birth. Should I be concerned? I have a Dr's appointment tomorrow and will be asking him...just wanted to know if anyone else is experiencing this.
