I had a mammogram done 2 weeks ago and have been called back for another one and an ultrasound with the consultant next week. They said that there were changes from my last mammogram 2.5 years ago. I haven't noticed any physical changes or lumps but am now imagining feeling lots of things. My last mammogram was at the start of my cycle, this was mid cycle. Does that make a difference? I've gained some weight since the last one, could that account for it? I'm struggling to sleep or focus on anything at the moment.
