I realise that I'm being completely paranoid and crazy but this evening I've begun to worry about breast cancer. My breasts have changed so much in the last few days - my nipples are raised and red, I have Montgomery's tubercles around them and the aerolas have darkened and expanded. I'm trying for a baby and have lots of pregnancy symptoms including no craving for coffee, severe exhaustion, bloated tummy and tender breasts. Please can someone tell me to get a grip. My period is due in a week.
