I know many people get sore boobs when they're period is about to start. However, not me, or never before I got pregnant, anyway. I remember it very distinctly that I knew something was up because my boobs were so sore. It's also how I knew something was wrong when that symptom went away. Since those times years ago, I'll get the sore boobs maybe once or twice a year. It doesn't last but it always makes me wonder - is my body trying to implant a baby? This is happening right now and I'm sure my period is coming any day now but thought I'd share. I don't let it mess with my head too much but you always have that twinge of hope, no? P.S. I don't recommend looking up the word "sore" in Google Images.
