Hi Laura,
Nothing you can do until Monday & worrying won’t change anything, but you are totally right to get it checked out.
Most likely it’s nothing serious & possibly related to recently discontinuing breast feeding. Bc would be the Least likely reason for it.
If your Dr refers you to the breast clinic, then that would be usual procedure, so don’t read anything into it. The breast clinic is for all breast conditions & they are the experts in getting it sorted out.
Chances are, all is well, but do get it checked out.
