hair dying second trimester

Sierra
I have a question, is it safe to dye your hair in the second trimester? I have a box of ammonia free hair dye that I want to use and I really want to get my hair back to the natural color without having a ring of growth around my head!! I know it should be in a well ventilated area. Should I be good to do it? I've read online that it is fine, just want to know what you all think.
