Post interview anxiety?

I had an internal interview on Tuesday for a position that the hiring manager urged me to apply for given my qualifications and relevant experience for the role. I was really nervous throughout the interview and it wasn’t my best performance, however on paper I am more than qualified. I was gutted I didn’t say a lot more once the interview was over and I felt like they probed me quite a bit in the process. She said she would contact me within a week to let me know the outcome. I know it hasn’t been a week yet but is no news good news in this scenario? Or would they have contacted me already if it was a yes given that this is an internal role?
