Changed my career choice help!!?

I recently got a place at 3 colleges and have now chosen my a levels choices and have accepted to the college i chose. I took history, law and english literature and english language. I wanted to be a barrister. But now i have been looking at a website and have found midwifery looks really interesting and i think i would love to do that. Shoud i go ahead and ask to change my options or wait to see if i change my mind because i have been wanting to be a barrister for year now. But i don't think that is me. Ohh im so confused. Help please
