Dying hair when pregnant!

Kirstie • Beautiful baby girl. So grateful and blessed every day <3
Ladies! I have dark brown hair and have soooo much grey hair that grows  soooo fast! It's really noticeable and I usually have to dye my hair every 2-3 weeks! I didn't even think about this before I became pregnant. What does everyone think about dying your hair when pregnant and does anyone have any ideas of what I can do?
