Help!!

I was blonde for like 9 years and when I found out I was pregnant I attempted to dye my hair my natural brown so the blonde chemicals wouldn't affect the baby... well i dyed it brown but it came out black 😭😭😭 I really hate to feel this ugly during my pregnancy, I should be enjoying it. Any tips on what I can do to make it brown????

Here's some pics of what I got and what I was aiming for
