How long does it take for the uterus to start growing during pregnancy?

In the early stages of pregnancy, some people may experience abdominal pain every now and then in addition to amenorrhea and nausea. The physiological causes of pain in the early stages of pregnancy are generally implantation pain and pain caused by uterine enlargement. On which day of pregnancy does the uterus start to expand? How long will the pain last during pregnancy?

How many days into pregnancy does the uterus begin to expand?

In early pregnancy, the uterus looks like a red grapefruit.

4 weeks of pregnancy: In the first month of pregnancy, the size and shape of the pregnant mother's uterus have basically not changed much compared to when she was preparing for pregnancy. But the endometrium begins to become softer and thicker, and looks about the size of an egg. At this time, the pregnant mother's hormone metabolism begins to be disordered. More sensitive pregnant women also begin to experience nausea, vomiting and other early pregnancy symptoms. Some expectant mothers also experience fatigue, fever, chills and so on.

8 weeks of pregnancy: As the pregnancy weeks increase, the mother's endometrium gradually becomes looser and the cervix thickens to protect the uterus. Generally, the first prenatal check-up is carried out between 8 and 12 weeks of pregnancy. The items generally include consultation, accurate measurement of weight and blood pressure, listening to the fetal heart rate, urine test, blood test, and checking the size of the uterus.

12 weeks pregnant: In the third month of pregnancy, the mother's uterus looks like a red grapefruit. The uterus gradually expands as the fetus grows. The fundus can be touched above the ischial tuberosity. The expanded uterus begins to be compressed by the bladder and duodenum located in the front and back. The bladder capacity is reduced, and frequent urination occurs, and there is always a feeling of incomplete urine.

How long will the pain last during pregnancy?

Most pregnant women experience abdominal pain during the first three months of pregnancy. Experts point out that most pregnant women experience abdominal pain at this time, and the main reason is the enlargement of the uterus. Therefore, as the fetus gradually grows and develops, the expectant mother's uterus will also expand, and the expanded uterus will continue to stimulate the outer edge of the ribs, causing the expectant mother to have a dull pain in the lower abdomen.

Abdominal pain caused by uterine enlargement in early pregnancy is a normal physiological phenomenon and does not require special treatment. Expectant mothers do not need to worry too much.

Abdominal pain one month into pregnancy is one of the normal reactions in early pregnancy. It is caused by the expansion of the uterus and stimulation of the bones. Pregnant women usually feel a vague stretching pain in the abdomen. If the condition is mild, it will improve on its own after rest. Professional doctors point out that if there is no vaginal bleeding or rupture of amniotic fluid in the early pregnancy and the baby is developing normally, pregnant mothers do not need to be overly anxious and worried, because it is a normal uterine contraction.

However, if the abdominal pain is intermittent, or there is continuous lower abdominal pain, such as the pain before or during menstruation, and is accompanied by vaginal bleeding, this may be a pathological condition during pregnancy, commonly pre-bleeding or ectopic pregnancy. At this time, pregnant mothers must go to the hospital in time for medical treatment and medication to prevent the condition from worsening or causing miscarriage.
