Dying your hair

Hello ladies, 
I need your advice/opinion! I'm currently 22 weeks pregnant with twin babies. My pregnancy was a surprise & finding out I'm having twins is a bigger surprise! 😊 I also have a 5 and 3 year old and have been a bit stressed planning the arrival of our twins. My hair is turning back its normal color on top and added a ton more grey hairs. 
I want to dye it so bad but I've heard it's bad to do so while pregnant. I never died my hair while pregnant with my older two but feel the need to do so now 😒 What do you ladies think...Dye it or don't dye it?? Your opinions are appreciated, please NO rude posts!
