Sore breasts

Monika
So for the last 2 months 10-12 days before my period my breasts are getting very sore. I mean, it gets to unbearable point, I can't be sitting calmly without being in pain, not even talking about walking. It's just getting to the point that I don't even know what to do, it's very frustrating as for 1/3 of the month I can't do simple things without being in masive pain. I stopped using pill last November, and we are trying to conceive, also I started to use folic acid. Is anybody else experiencing same thing or maybe been in the same situation?
