Lump found in right breast

Hi all

so I am new on here, just recently I found a lump in my right breast (by accident) I reached over to itch under my arm and felt the lump. 
it’s about an inch away from my armpit, topside of my breast, I think I may have found another one too

I have been to my doctors, the doctor checked me over and just said she was referring me to have it investigated further at the hospital and it was a 2 week referral. 45 minutes later I got a phone call with an appointment for in a weeks time. 

I know people say not to think the worst and I’m doing my best not too, but there is a part of me that is worried sick. I’m trying to keep my mind off it with work and wedding planning (me and my partner at getting married in August next year)
