Does the disappearance of early pregnancy reaction mean that the fetus has stopped growing?

If the reaction or symptoms disappear during early pregnancy, you must be alert. It may be caused by fetal arrest. Because of the influence of hormones after pregnancy, certain symptoms will appear. When fetal arrest occurs, progesterone will suddenly drop, causing some symptoms to disappear. At this time, you should go to the hospital for examination in time to avoid greater harm.

After pregnancy, the human chorionic gonadotropin (also known as HCG) in the body will rise rapidly. This hormone will cause a decrease in gastric acid secretion and a prolonged gastric emptying time, causing nausea, vomiting, fatigue and other discomforts. HCG proliferates rapidly after fertilization until the 8th week of pregnancy, then slowly decreases until the 18th to 20th week when HCG levels remain stable.

After pregnancy, the body's estrogen and progesterone levels rise rapidly, stimulating the mammary glands and causing reactions such as breast swelling. When fetal growth retardation occurs, the fetal bud or fetus in the gestational sac has stopped developing and gradually atrophies. The levels of HCG, estrogen and progesterone will drop rapidly, reducing the effects on gastric acid secretion, gastric emptying and breasts, and the feeling of pregnancy reaction will gradually decrease. Therefore, if the early pregnancy reactions such as nausea and vomiting disappear and the feeling of breast swelling weakens, you should be vigilant, as these phenomena can be regarded as early symptoms of fetal growth retardation.

Abdominal pain and cramping

During pregnancy, expectant mothers may experience mild abdominal pain and dull pain at certain stages, which is normal. However, if abdominal pain occurs suddenly and is accompanied by abdominal cramps, you must take it seriously and go to the hospital for consultation and examination in time.

However, some patients with fetal growth retardation do not show any signs and directly experience spotting or miscarriage, or the fetal growth retardation is discovered through routine B-ultrasound examination without any symptoms.

Fetal growth retardation is also clinically known as "missed abortion", which refers to the death of the intrauterine embryo at a certain stage of development and the cessation of further development, resulting in the termination of pregnancy before 28 weeks. If the expectant mother has amenorrhea for more than 6 weeks, but no gestational sac is found in the uterine cavity; or the gestational sac has been deformed and has no tension; if the diameter of the gestational sac exceeds 4 cm, but no fetal bud is seen; if the fetal bud exceeds 1.5 cm but no fetal heartbeat is seen; or if a routine examination finds that the normal fetal heartbeat has disappeared, it may be diagnosed as fetal growth retardation.
