I have a three year old daughter born june 2006 in which i started taking depo provera shots. i had my last shot october 2008. i havent had a period since july 2006 and its now june 2009? i noticed that my breasts were little bit sore especially on sides and underneath? and then today i noticed that the areola aruond my nipple looks larger than usual. i took a pregnancy test.. negative? im confused? and dont have periods to rely on? what should i do?

3years no periods? sore breasts? larger areola? negative test? My husband thinks its all in my head? but im not sure?
