okay, so I'm a cosmetologist, and in my second trimester I started dying my hair again, my OB said it was okay, I left it alone in the first trimester, now I'm in my third and people keep saying you shouldn't be dying your hair, well for one, my baby boy is very healthy, two I've done my research and asked my ob, you HAVE to be in a ventilated Area when you dye your hair, but that's common sense, and three, I'm getting really tired of being judged, I also have a medical background and know a little more and people seem to forget that, and on top of it I start sonography class in August, has anyone else ever felt judged like this...?
