Pregnancy and hair coloring

Sarah • I have a beautiful 10 month old baby girl in heaven watching over her family and an amazing 3 month little boy ♥♥♥♥
This is my second pregnancy and I can't seem to remember what is okay to do and what is not. My hair needs to be colored (well I want it done too). I can't remember if it's okay or not. I read all kinds of things but they are all contradicting to each other. Please help if you have asked your doctor. I don't see mine again until Monday and I'm trying to get it done this weekend.
