Breast lump, ultrasound then biopsy ..

Hello,

so I noticed a lump and it's been around a while which I thought was my glands as I has changed contraception .. I went to my gp finally last week who referred me straight to the breast clinic and I booked the first available app which was on Friday. 

the consultant examined me then I had an ultrasound and then they took a biopsy.

the consultant said I would have to come in for my results on the Thursday (tomorrow) i had to chase that up on Monday as no one has confirmed appointment time. The only appointment she could offer me was early evening and she said it's because my results will be discussed in a meeting Thursday morning? Is this normal? Has anyone else had this and it be a normal result? I'm 27 with two children and no family history of breast cancer .. I haven't slept at all tonight I'm just so worried now :( !
