Introduction

In general, symptoms of fetal demise at 13 weeks of pregnancy may include disappearance of early pregnancy reactions, cessation of breast enlargement, lower abdominal pain, vaginal bleeding, and backache. If fetal demise occurs, an induced abortion can be performed under a doctor's guidance to remove the nonviable fetus. After the procedure, avoid excessive mental stress and consume nutritious foods to help your body recover.

　　Under normal circumstances, at 13 weeks of pregnancy, symptoms of fetal demise may include disappearance of early pregnancy reactions, cessation of breast enlargement, lower abdominal pain, vaginal bleeding, and backache. The details are as follows:

　　1. Disappearance of early pregnancy symptoms

　　After embryonic development stops, the level of human chorionic gonadotropin (hCG) in the body decreases. As a result, pregnancy-related symptoms such as nausea, vomiting, and fatigue gradually subside and disappear.

　　2. Cessation of breast enlargement

　　Levels of progesterone and estrogen in the body drop significantly. Stimulation of the mammary glands and alveoli decreases, causing the breasts to stop enlarging.

　　3. Lower abdominal pain

　　Once fetal development ceases, the uterus no longer grows with the fetus and gradually returns to its normal size, often accompanied by pain.

　　4. Vaginal bleeding

　　Fetal demise at 13 weeks of gestation is considered a case of missed abortion, which may be caused by embryonic abnormalities or chromosomal issues. When embryonic development stops, the endometrium may begin to shed, leading to vaginal bleeding.

　　5. Backache

　　Fetal demise at 13 weeks may lead to spontaneous miscarriage. Vaginal bleeding is a common sign of miscarriage. Backache may result from uterine contractions, which help expel the embryo and endometrial tissue from the body.

　　If fetal demise occurs, induced abortion can be performed under a doctor's guidance to remove the nonviable fetus. After the procedure, avoid excessive mental stress and consume nutritious foods to support physical recovery.

A bloated and tight abdomen at 13 weeks of pregnancy may be a normal phenomenon, but it could also indicate an abnormal condition, such as intestinal gas or threatened miscarriage. In addition, gastrointestinal disturbances or fetal growth may also cause a bloated and tight feeling in the abdomen. Pregnant women should ensure adequate rest and engage in moderate exercise during pregnancy.

What is the size of the uterus at 13 weeks of pregnancy?

At 13 weeks of pregnancy, the uterine size may be approximately 100×75×80 mm. The uterus is the organ in which the fetus develops. A normal pregnancy lasts about 40 weeks. At 13 weeks gestation, as the fetus grows, the uterus gradually increases in size, typically reaching around 100×75×80 mm. However, the fetus is still within the pelvic cavity, so the abdomen usually does not appear enlarged yet.

Will the NT value be larger if measured at 13 weeks of pregnancy?

The NT value at 13 weeks of pregnancy is generally larger. The NT scan is performed between weeks 11 and 13 of pregnancy to measure the thickness of the fetal nuchal translucency and assess whether the fetus has any abnormalities. The normal range for fetal nuchal translucency should be less than 2.5 mm. As the fetus grows and develops, the nuchal translucency thickness increases, so the NT value at 13 weeks of pregnancy tends to be higher than earlier measurements.
