Amazon registry?

I’m planning on using amazon again for my registry but I’m so early in my pregnancy that I just kind of want to keep it on th DL for now. I know you have the option to make your registry private, give out a link to anyone who’s interested, or you can make it public. I’m leaning towards making it private just to use as a list for myself on what things I might need but wondering if I can change the status of my registry later on when I’m ready to share?
