Hair help!!!

I have naturally blonde hair and I wanted to return to this color but I have been dying my hair black for about four months (so 3x dye). I used Color Oops and it stripped away a lot of dye, leaving it a coppery color. I immediately put blonde dye over this, but the only thing that got lightened were my roots. I look obnoxious and I don't know what to do, should I try a other box of Color Oops or should I dye my hair brown & wait until I'm no longer pregnant (July) to bleach my hair??
