Doctors seen breast dimpling

Hi everyone. 
I've been to the doctors today due to have discomfort under my arm and side breast. 
it hurts if I reach forward or up or knock my right boob. 
The paramedic at the doctors checked me over and couldn't feel any lumps but she said I had some dimpling. 
Obviously I'm now very worried. I have 2 young children and my life is flashing before my eyes :neutral:

I've got home and checked myself in the mirror. Done all the positions she asked me too and I can't see any dimpling. 
I have lots of stretch marks where I've had children. Lost weight and gained weight. 
Im wondering if she has seen these and maybe thought was dimpling. Or I hope that's what it is. 
she's referred me to the breast clinic and said I'll get an appointment within 2 weeks so I'm happy about that. 
I've added  pictures for you to see. Please excuse my saggy boobs haha.
