Body Changes That Occur During 4 Months Pregnant
As previously mentioned, during 4 months pregnant, pregnant women will be more visible because their stomachs are getting bigger, so pregnant women may need to start wearing special clothes and pants for pregnant women.
When you are 4 months pregnant, pregnant women may also start to feel new complaints, namely heartburn or heartburn. This complaint may be felt because pregnancy hormones can cause the valve above the stomach to relax, allowing stomach acid to enter back into the esophagus.
This condition can also be exacerbated by pressure from the growing uterus, so that complaints of heartburn or heartburn may be felt.
In the 4th month too, changes in hair and skin will occur. The changes caused can be different for each person, some are pleasant, some are not.
In hair, for example, some pregnant women may feel that their hair is thicker and shinier than before. However, there are also pregnant women who actually experience hair loss when they are 4 months pregnant.
Changes that occur in the skin are also the same. There are those who experience stretching and hyperpigmentation, others whose skin looks brighter, beautiful, and shiny (pregnancy glow).
Pregnancy hormones at this time not only affect the physical condition of pregnant women, but also affect the ability to think, remember, and focus. This is also known as the pregnancy brain. If pregnant women experience this, there is no need to worry, because this is normal.
When you are 4 months pregnant, pregnant women may also feel pain that often occurs in the thighs or legs.The complaint, called sciatic nerve pain, is thought to be caused by the enlargement of the uterus which then presses on the sciatic nerve, which is the largest nerve in the body which is located from the bottom of the uterus to the feet.
