Yes, that's normal @youngdogmum. They need the path reports for the MDT to make recommendations. Depends where you are, but it seems likely you will be referred to an oncologist as soon as the results come in.
My cancer was ILC too, but i was 43 when I was first diagnosed. It's interesting that you surgeon is recommending a full axillary clearance straight up. I'm wondering if you are in a regional area where that procedure is more common as there is often no facilities for sentinel node surgery or if that is your surgeons usual approach or if they feel you are likely to have second level node involvement? It's worth asking about that as a full clearance can be problematic later and many surgeons try to avoid them unless it's absolutely necessary.
