The symptoms that women have for PMS are apt to changing on their own for no apparent reason. Its nothing to worry about or stress over. I used to have barely any symptoms at all and now I may have PMDD. Its just what our bodies do.

If you are using protection properly or on birth control (both would be best lol) I would highly doubt you are pregnant.

Do not worry about being pregnant until you are five days late or more. Then make sure to test with your first morning urine. Best of luck to you!

ok. well i took a test 5 days before period and it was neg. but i heard its more accurate after missed period. well thanks for the advise.

ever since i started birth control pills my breast do not hurt that often before my period. I LOVE IT! One less premenstrual symptom is very ok with me!

most times VERY sore breasts is one sign of pregnancy...I'm sure you're fine but to ease your mind you can take a preg test if you'd like.

i used to get sore breasts before periods and then i stopped getting that symptoms for a couple of years and now only my right boob gets sore... i guess it can change for no reason
