4 weeks 4 days pregnant, why have my breasts stopped hurting they where hard in places and now its going down? does this mean the pregnancy is ending?

Not always: Although it is considered normal to have breast tenderness in early pregnancy, not having it does not always equal unsuccessful pregnancy or impending miscarriage. Before making any conclusions about the status of the pregnancy you should visit your ob/gyn and be evaluated with a vaginal ultrasound. This will be able to determine whether the pregnancy is ok or not.
