Hair loss

I'm only 7w1d and my hair has been falling out more than normal. I read online that it is supposed to only fall out after delivery. I also read that it can possibly mean that you aren't getting the proper amount of nutrients or maybe it's because the baby is taking all the nutrients. I also read that if you're having a girl it tends to fall out more during pregnancy. Anybody else experiencing this? Anybody having a boy or girl and can testify to it?
