How long is too long with no poo?

EV
Hi, just had my daughter 5 days ago, was released on day two, but she hasn't had a poo since then. I read that it could be normal Togo a day or two on the breast, but now I'm getting worried? Anyone with any reassurance out there, or is this a bigger problem? Making my first pedi appt today and I will bring it up. Just worried until then!
