Hollylee,
Perhaps it's best to wait. I'm just a little jumpy cause I lost my favorite phal to root rot because I waited till the blooms went by. You actually have a clear pot, so perhaps you can see the roots?
I have repotted in bloom before and it's a huge chore, but it can be done. However, you may or may not lose some blooms. I don't want to make that happen for you. Just be careful it doesn't stay too wet and you should be fine. Again, I wasn't thinking at the difficulty, but about my loss. Sorry!
Tut tut, carry on!
