Highlights at 10 or 11 weeks ok?

I am in dire need for highlights and I wanted them done by Christmas. I know you're cleared after the first trimester for highlights because they don't touch your scalp like hair dye does. The only time I can get in is around 10 or 11 weeks and it's done at someone's home, so there aren't tons of fumes, since she will just be doing my hair. 
What do y'all think?
