I am a mom of 3! I had my period on Dec 27 and am currently supposed to be ovulating (per online calculator) my breast have been so sore the past 3 days and that's just out of the norm for me. The only time my breast hurt are the week before my period. Can your body just change and start having sore breast when it's never before done that? Or am I pregnant? I mean, I don't know what to think as this isn't normal for me.
