Ok where to start

I have been having huge health anxiety about breast cancer. So much so I got a breast health check including mammogram through Bupa and the spire. 5 days later I have noticed a little kid of dip in my outer left breast. It is not there when I lean forward or lift my arms. But it's there when I stand arms down my side. It might of always been there and I'm hyper focused on it. 

I asked Google and he said that the breast health is not diagnostic and it will not be found on the mammogram. But that's what i went for to see if any early signs. Google is scary I looked at some images and it matches some. When I smooth the skin it's not there. I do have a dip in my right but was confirmed fibrodeama. 

I'm worried to see the GP because they will think I'm stupid. It's like a flat tiny indent and when pressed feels hollow. Also I can pinch the skin. 

Should I just wait for results as it will of been picked up by the spire.

Kind regards a very scared 48yr old who become a nana for the first time today and all this has took my happiness away
