Bleaching hair at 39 weeks????

So I’m 39w tomorrow and I want to dye my hair, but I have naturaly black hair and will have to bleach it to get this color, I keep seeing mixed reviews. Some say it’s safe, some say it’s not, and others say don’t touch the scalp bc it will get in my bloodstream and harm the baby. Or that my hair will fall out bc of my hormones. can some one pls help 😫😫
