I have been symptom spotting like mad and have been examining my boobs every day looking for spots, viens, growth, etc. I was in the bathroom doing my usual inspection and I noticed that my left nipple was dark brown and the other pink. I ran in the bedroom and said to DH "look at my nipples, one is darker than the other" he had a good look and told me they were the same colour so I had another look in the bedroom mirror. He was quite right, they were both pink. I felt like a bit of a t*t myself. It must have been the light in the bathroom. DOAH!
