I’m scared I hurt my baby with hair dye

I posted yesterday about if it was safe to dye my hair. I dyed it mahogany red and I didn’t know anything about ammonia free so I dyed it permanently and I missed pieces but now I’m scared to touch it up because I started reading things about the chemicals being bad for the baby. I’m 23 weeks and idk if I should find a dye that is ammonia free about the same color? Or should the one I have be ok since most of the pieces I missed aren’t in my scalp. I regret not waiting.
