What happened to my sore boobs?

Jennifer
I get sore boobs a few days after ovulation every single month until the day after I start my period- including when I found out I was pregnant with my son. This time they were sore up until 6-7dpo and today nothing! What gives? I had four high fertility days and god my peak fertility day via clearblue digital. Anyone experience this? I can't think of any time I have and I'm 29 so I've had my fair share of periods to compare it to. Thanks!
