How Can Breast Bruising And Pain Be Treated?

i've been taking reclipsen birth control. and every since i started my 2nd pack, my breasts have felt like their bruised. not so much the nipples, but just the breasts themselves. i've been on it for 4 months now and the only time i notice when my breasts don't hurt is when i'm actually on my period. why is that? and what can i do to stop my breasts from hurting? they only hurt when i'm not on my period, as soon as i start my period, the pain goes away but as soon as it stops, the pain comes back again.
