nuvaring - really sore breasts

Hey all,
This is my 2nd month with the Nuvaring.. The first month was horrible, really sore breasts (as if someone stumped me everywhere) and really bad cramps for three weeks straight.. The 2nd time around the cramps are gone and so are the sore breasts - I thought.. After a few days they began hurting a bit again and it got worse uptil the point where they hurt as much as last time.. They feel really hard and heavy as well. I'm pretty worried..
Experiences and/or wisdom please

 

I've gotten really sore breasts before I think probably from birth control too. Its just your body reacting to the hormones.. if it continues you should talk to your doctor.. hope it gets better!
