Breasts don’t hurt in the second month of pregnancy. In the first case, it may be the case of embryonic termination and spontaneous abortion. As the progesterone in a woman’s body will increase after pregnancy and promote breast development, her breasts will present a feeling of swelling and pain. When embryonic termination and spontaneous abortion occur, the progesterone will decrease and the breasts will no longer be swollen and painful. In the second case, it is also possible that in normal pregnancy, the woman has adapted to the increase of progesterone in her body or wears loose and comfortable clothes, and after relaxing her mood and shifting her attention, she feels that her breasts are no longer swollen and painful. Although you can’t rely on breast swelling to predict the development of the embryo, try to go to the hospital for a gynecological ultrasound when the original swelling disappears. If the embryo is well developed and the fetal heartbeat is normal, it is necessary to strengthen the obstetric examination, and if there is embryonic failure or spontaneous abortion, it is also necessary to terminate the pregnancy in time.
