My name is Valerie and my breast have been very tender and sore. They itch all the of the time and has been this way for about 3 1/2 weeks. My last period was very irregular it was only here for 2 days and that was it. My nipples also itch constantly and are very sensitive and are always perky. Is this a sign of pregnancy? We have been trying since January to get pregnant with no luck so far and we are hoping that this a sure sign although I am very much in pain when it comes to my breast. :-)
