t m i.....

Ok, so please don't judge me, I just need advice. 
I'm currently 12 weeks and have a hair eating addiction. I eat the clumps of hair I find on the floor inside my house, which mostly consists of clumps of dog and cat hair. 
I've been doing this for many years. 
Will eating the large amount of hair I do on a daily basis affect the baby?
Thanks in advance, 
Sue
