Reasons for a big belly at 4 months of pregnancy

There are 40 gestational cycles in total, and four months of pregnancy is 13-16 weeks of pregnancy. Many mothers know that in the early stages of pregnancy, the belly is not obvious because the fetus is only the size of a fist. So how big is the belly at four months of pregnancy? Is it normal to have a big belly? Let’s take a look at the reasons why your belly becomes big at 4 months of pregnancy.

One size

At 4 months of pregnancy, the standard uterine height of expectant mothers is 16~20.5cm, the abdominal circumference is between 76~89cm, and the weight has increased by 4~5kg accordingly. However, your belly is slightly bulging now, and outsiders can see that you are pregnant. The fetus is about 12 cm long and weighs 150 grams, which is just the right size to fit in your palm.

What tests should be done in the 4th month of pregnancy

When you are four months pregnant, you need to do the following types of prenatal examinations to ensure the health of your baby:

1. Measure uterine height and abdominal circumference: These are items that expectant mothers must measure every time they have a prenatal checkup.

2. Routine urine test: This test can rule out diseases such as gestational hypertension.

3. Edema check: Pregnant mothers will have varying degrees of edema, but if there is obvious depression when pressing the lower limbs, and the edema does not subside after rest, you should measure your blood pressure immediately to prevent pregnancy-induced hypertension.

4. Down syndrome screening: It can detect whether the fetus has birth defects, such as Down syndrome, anencephaly or other chromosomal abnormalities. This method is more reliable and less damaging.

5. Listen to the fetal heartbeat: Hearing the fetal heartbeat means that the baby in the belly is alive. The doctor will only prescribe a series of test orders after hearing the fetal heartbeat.

Three nutrients

Four months of pregnancy is already the middle stage of pregnancy, and the nutrition of expectant mothers plays a particularly important role in the growth of the baby.

During this period, expectant mothers need adequate vitamin D and calcium to help the fetus's bone growth. Fish is a major source of vitamin D. If you can't eat fish, eggs also contain vitamin D. Sunbathing can also produce vitamin D, so half an hour of sunbathing every day is also fine.

The above introduces the size of the belly at 4 months of pregnancy. In fact, the size of the belly varies from person to person. Generally, the belly size becomes noticeable only at 5 or 6 months. It is not very big at the beginning, and you can't see it at all if you wear loose clothes. Some people's stomachs grow faster, while for some pregnant women, their stomachs don't look too big even when they are seven or eight months pregnant. It is actually not a good thing for the fetus to grow too large. It should be moderate. As long as the prenatal check-up is normal, there is no problem.
