Help?

Nicole

So I recently found out that I am around 4 weeks pregnant. I don't know if it's just because my hormones or what but I have a spot of hair that fell out on the top of my head. It's no bigger than a dime size about. I read that that can be normal but I wanted to see if other pregnant woman have experienced the same thing. Has anyone else notice hair loss while being pregnant? Also this wasn't an issue before I got pregnant.
