The saying is.. green on green equals black and blue
I was still pretty novice when I broke my first 2 horses.. and everything turned out okay. I made some mistakes that I don't make now, but you have to live and learn
Read & watch videos and learn as much as you can. You already say you have a trainer helping you, so that's a good start so the trainer can help you and her learn.
If it ever gets to the point where you dread going to work with her, that's the point where I would suggest considering getting rid of her and finding something that's more broke so you enjoy riding and build your confidence up.. but as long as you are happy and still excited to go work with her, then congrats and keep us posted on how things are going!
