Dying hair while pregnant?

Becky • Mom of 2 💕
This is my 2nd baby and I never dyed my hair while pregnant with my son.... and actually haven't dyed my hair in years. I just wanted to use a non permanent hair dye to cover a few grays and switch it up a little since I'm not feeling the hottest lol. What do you ladies think? I know they say it's safe after your 1st trimester... but just wanted to see what you all had to say!!
