Hair coloring while pregnant?

Julie
I'm the type of woman who loooooves to color my hair, not always natural colors, and my last coloring was a bit over a month ago. It was black and blue, now it is a greyish light blue with a mix of terquoise and a dull black.  
I found out I'm past 6 weeks pregnant and most suggest waiting to do any coloring until after the first trimester. I don't think I can handle this awful mess of a color on my hair for 6 more weeks! Had I known I was gonna be pregnant a month ago I wouldn't have went with such extreme colors! I soooo badly want to extract the colors and go for something natural. (My natural color is dark blond) 
Are there any natural or organic products I could use? 
I don't want to harm the baby, but my hair is driving me effing nuts!!!
