These are situations that appear without associated symptoms. and, for that reason, they are more difficult for parents to understand. This leads to creating states of unease and doubts about fertility.

To diagnose a deferred abortion, the doctor will perform a vaginal ultrasound in the first trimester. Depending on the gestational week in which the pregnancy is found, it may be necessary to repeat it before making a definitive diagnosis.

The value of the chorionic gonadotropin hormone (pregnancy hormone) begins to decrease about 10 days after the development of the embryo has slowed. For this reason, performing a blood test or a pregnancy test has no diagnostic value.

  • Endocrinological, blood or immune diseases. Certain diseases that affect all the organs of the body and usually have consequences during pregnancy.
