Hair color in 3rd trimester

JFluvsJD80

My doctor gave me the ok to get my hair colored way back when and I got it done at the very beginning of the second trimester (regular single process). The color came out same as it always does.

Now that I'm ready to do it again, I've been reading about the color coming out slightly different or funky at different stages of pregnancy. Not sure if there's any truth to this, so I wanted to see if anyone had experience with it. 

Anyone get theirs done recently? How'd it turn out?
