I am 37 yrs old.... I had the Mirena for 5 yrs... The Mirena was removed in June 2009... Afterwards I had major blood-clotting during my monthly(s) and had a biopsy done which showed I am (was) still able to conceive.... My Husband and I are trying to have a child.... I have not had my monthly since mid Feb. My breasts are sore & tender... Is it Pre-menopause or ????
