I wouldn't worry about it. Not every pregnant woman gets all or any of the signs. Absence of 1 pregnancy symptom is nothing to be concerned about. I also think that some signs tend to be power of suggestion too. I never had sore breasts with my first 2 pregnancies until I started going online and talking to women who were TTC, suddenly I was having sore breasts when pg and during AF though I had never had sore breasts during AF before. Since the birth of my last child my breasts no longer get sore.
