Secondly,PCOS not only increases chances of heart problems,diabetes,high blood pressure
and cancer of the lining of the womb (known as endometrial
cancer),but it can cause breast tenderness also.Are you taking the treatment for your PCOS?
I sincerely advise you to consult a gynecologist and discuss this with hi,/her.You can switch to some other birth control measure and see if the symptoms improve.
