Mark on breast that looks like a finger mark

I check my breasts regularly and also look through the mirror.

I noticed last week a mark that almost looks like a finger print 

called gp and got a appt same morning.

took a photo so I knew she was seeing what I could see also noticed sometimes when I'm laid down my opposite nipple lays down and the skin around almost looked twisted again took photo of this.

when I showed her both photos she did say that doesn't look normal.

can I look at them with my own eyes. So she did and had a little touch said they both looked perfect and nothing to worry about. I asked can you see what I'm seeing and what is in photo. She said no and did I believe my photo or her own eyes as a Gp.

went on to ask about my periods and when I told her I was bleeding too frequently and had pains she straight away referred me to a gynaecologist as she couldn't see to give me an internal as said I looked like I had falling in vaginal wall.

I didn't want referring to there I wanted my boob worries to be checked. 
the mark is still there should I keep an eye on it and if it worsens insist on been seen by somebody else.

or shall I just take her word for it.

in all my years of checking I've never once been to the gp because I've noticed anything so this is obviously different for me
